Most of the places have been found in the current day, those that aren't and maybe need a further hunt are Bacton, Erpingham, Frettenham, Hunworth and Trimingham.
Once the map is open; If you click on the left menu it will highlight that Post Office with a picture. You can also click on the markers and choose 'Street View' to whisk you there. The view of the camera may not always be as desired and may require you to rotate/pan the camera around etc.
Where the current location is unknown, ie I have not found it, the Street View will take you more or less to the centre of town.
Here is a KMZ file that contains the map ready for use in Google Earth. You will need to unzip it first...
Gibraltar was known to the ancients as Mons Calpe, one of the Pillars of Hercules. Ptolemy first determined its latitude, and the correctness of his calculation is corroborated by the observations of the present day. The conspicuous form and isolated position of this rocky promontory, which stands like Nature's monument with all its rugged steeps at the entrance to the Mediterranean Sea, made its name familiar to ancient navigators, and we find the Rock referred to and described by both Greek and Roman writers.
Frederick Sayer 1865
he 'Rock' is less than three miles long and less than a mile wide but has been argued over for a very long time. Currently it remains today as a British Overseas Territory. It rises to around 1400 feet and is made of Jurassic limestone.
Gibraltar had been a Spanish possession until the early 18th century but in 1704 a combined Anglo-Dutch force, in support of Charles III, took the rock into British rule. During the 18th century there were three sieges including the Great Siege between 1779 to 1783 and many of the defences still survive today.
In 1848 within a cave on the north face of the rock they found the skull of a woman. These remains were later known as Neanderthals after a similar skull was found in Neanderthal (Neander's Valley) in Germany.
World War II saw Gibraltar being used as the navel base for the Mediterranean Task Force and as a stop for supply convoys. They also built a solid surface runway and the rock became a major fortress with tunnels to store guns and ammunition as well as to provide a hospital and barracks.
The definitive stamps
The first of Gibraltar's pictorial stamps was fashioned by Captain H. St. C. Garrood for the KGV 1931-33 issue. This was reused for the KGVI set and other designs were added to make up the basic collection of 14 stamps. The designs were inspired by the views shown on the Beanland Malin & Company postcards. 
With the Multiple Script CA watermark the first of these stamps were released on 25 February 1938 and printed by De La Rue. There are a great deal of variations in the KGVI stamps, with differing colours, watermark alignments and perforations. I will focus mainly on showing the designs for the most part but will mention some varieties too.
Skipping first to the 1d brown value; this is the 'Rock of Gibraltar' design, which as mentioned above was first used for his father's stamps. It comes in various colours from pale browns to dark chocolate browns and perforations 14, 13 ½ and 13. The same design was used for the 1½ d carmine (P 14 & P 13½) and the 1½ d violet (P 13). This scene would seem to be from the bay as per the old postcard.
Turning to the 2d grey, this was produced in perforations 14, 13½ (also with sideways watermark and a high catalogue value), and perforation 13. They again reused the design in 1944 this time as the 2d carmine - here the view is of 'The Rock Northside'.
'Europa Point' is featured on the 3d light blue stamp which was produced in perforations 13½, 14 and 13. The perforation 13 is also listed in a greenish blue colour by Stanley Gibbons. Like before the view was used again for the 5d red-orange of 1947.
For the next design we have the Moorish Castle on the 6d carmine and grey-violet which was first issued 16 March 1938. The different perforations were 13½, 14 and 13. There is also a scarlet and grey variety (1945) as listed by Stanley Gibbons. This design was only used on the 6d value. The castle dates to the Medieval period with the most prominent feature being the Tower of Homage. It makes for a dominant and strategic position.
Next up is Southport Gate in black and green for the 1/- value. Perforations were 14, 13½ and 13. Underneath it is the gate shown on a picture postcard. Now consisting of three gates, built at different periods, within the Charles V Wall which dates to the 16th century.
For the 2/- design, Garrood chose the Eliott Memorial. Perforations were 14, 13½ and 13. Colours black and brown. George Augustus Eliott (1717-1790) was a British Army officer noted for his defence of Gibraltar during The Great Siege.
The 5/- features Government House in black and carmine. Three perforations were made; 14, 13½ and 13. This particular postcard is one from Beanland Malin & Company that inspired the design.
Government House is the name given to some of the residences of Governors-General, Governors and Lieutenant-Governors in the Commonwealth and the British Empire. It serves as the venue for the Governor's official business, as well as the many receptions and functions hosted by the occupant. 
The last of the pictorials is the 10/- showing Catalan Bay in black and blue. Just two types of perforation this time - 14 and 13.
Catalan Bay (Catalan: La Caleta) is a small bay and fishing village in Gibraltar, on the eastern side of The Rock away from the main city. During the nineteenth century only fishermen were permitted to live in Catalan Bay. They were required to have a fishing permit granted to them by the Governor and only a limited number of permits were issued. The families who live in the village today are mainly descendants of these Genoese fishermen, and are colloquially known as caleteños. 
Finally here the ½d green and the £1 stamps simply feature the King's portrait. Both were perforated 13½ x 14.
For completeness; shown above are the other colours and values mentioned earlier with repeat use of the designs.
Next I will show some examples on cover with different features and rates, I think they make for attractive items.
Here we have a 1940 (24 May) airmail cover sent to Cambridge in the UK. It shows a purple triangular censor stamp with a central 'g'. Also there is the slogan 'Gibraltar - The travel key of the Mediterranean' applied by a roller machine. From 30 January 1940 the first ½ ounce was 5d for airmail letters. 
Due to the war the civilians were evacuated to Britain, Jamaica and Madeira. Gibraltar was fortified and by 1942 there were over 30,000 servicemen and women stationed there.
Shown above is another World War II period cover which has a triangular censor mark in purple. Sent to Kent in the UK, but the date is not legible, this has a 'Field Post Office' cancellation. The Air Mail rate for letters to the UK from 28 December 1940 was 6d. 
Two examples above of a circular type censor mark in different colours. These were posted in 1943 and the face value of the stamps is 6d as expected. They are cancelled with the Field Post Office circular date stamp.
A 'Field Post Office' circular date stamp with unclear date but with an 'RAF Censor 160' mark in blue. The R.A.F. personnel were not allowed to use Great British stamps from October of 1943. This was subject to the introduction of a lesser 3d rate per half ounce to the UK. 
In an effort to show a clearer image of the Field Post Office cancellation I traced one out in Photoshop. Field Post Office 475 opened 2 December 1940. Note that this cancellation was still in use for some time after the war ended. Office 475 closed in 1947 but the date stamp was kept and was then used by the civilian post office to cancel force's mail as can be seen above.
Above we have an example of a registered letter to Sheffield in the UK, dated 14 August 1945.
Here we have multiple stamps on a cover to Stockholm, Sweden, marked with Gibraltar CDS on 18 April 1950. The face value of the stamps is 8½d. Air Mail rates from 1 June 1949 to Europe was 5d for the first ½ ounce and 3d for each additional ½ ounce.  If this weighed up to 1 ounce then it's ½d overpaid. But more likely it was simply to gain the stamps on cover, also suggested by the arrangement.
Above is the 3d blue on an airmail cover to London in the UK. Dated January 19, 1953 this has a roller machine postmark. The rate to the UK from 1 June 1949 to this time was 3d for the first ounce. 
New Constitution 1950
In 1950, the Gibraltar Constitution order and Gibraltar Election Rules ended the Governor’s monopoly of legislative authority, with the formation of a Legislative Council. Subsequent amendments allowed for a majority of elected members in the assembly. 
For 1 August 1950 these four values; the 2d, 3d, 6d and 1/- were overprinted in commemoration of the Inauguration of Legislative Council. The shilling being in red ink.
Finally we have the New Constitution set on a registered First Day Cover, sent to New York and dated 1 August 1950.
his is an old article I found in a copy of The Straits Times from 1935. I thought it was an interesting read and it mentions a rare Gibraltar error on a sheet full of 120 stamps. It also briefly mentions Captain H. St. C. Garrood who designed the nice views of Gibraltar for the KGV definitive and later the KGVI definitives. Hopefully no one will mind me reproducing this here.
Stamp Collecting, Gibraltar Jubilee by Fred J. Melville
o matter how often one has passed outward bound or homeward, the sight of Gibraltar brings every-one on deck.
We are now within a few weeks from the philatelic jubilee of Gibraltar, which has had its own postage stamps from New Year's Day, 1886. For the first forty-five years they had always been of the conventional typo-graphed Queen's Head or King's Head of standard patterns.
It came as a surprise four years ago when a change was made to an intaglio view series for the low de-nominations. This was designed by Captain H. St. C. Garrood, and the printing was still done by De la Rue and Co, who will celebrate their jubilee as printers of all the Gibraltar stamps except this year's silver-jubilee series.
It is just a pity that the Gibraltar jubilees did not come into the jubilee groups entrusted to De la Rue, seeing that the four denominations of this year are the only Gib stamps that are not of this firm's manufacture.
Gibraltar is a favourite Colony with stamp collectors, partly, no doubt because of the fascination of its impressive history and unique position. But also largely because its philatelic emissions are still not too difficult for the average collector to encompass.
In the fifty years since the first issue our "Gibbons" only lists 117 different stamps, and "Whitfield King" 104. Of these few are at all expensive, while only one is a rarity.
The rarest stamp of Gibraltar is by way of being a real curiosity. It is peculiar in that the design was printed, but the value or denomination was not. The issue of 1880 was printed from a key-plate bearing the design common to all values.
The denomination in the old Spanish currency of centimos was added afterwards from a duty plate. One sheet of 120 stamps printed in carmine for the 10 centimos (about 1d) stamps missed going through the press the second time to have the value printed in, so the value tablet remained blank.
This is one of the very rare instances in which a stamp error has slipped past the lynx-eyed examiners at De la Rue's.
From the stamp stock at Gibraltar a post-office clerk was about to serve a customer with a ten centimes stamp when he noticed the label was blank. He looked at the sheet and found all the 120 were alike. He put it aside, and served the stamp from another normal sheet.
As it would have been against the post-office rules to buy the freak sheet himself, he arranged for a friend to come in and buy it. The friend did, and after a little while I placed the freak stamps with a speculative philatelist visitor to the Rock, at (it is said) about £3 apiece, quite a nice profit on stamps bought at the post-office at a penny each, but still out of all proportion to their value on the stamp market today; the stamp is priced at £90 in the new Gibbons catalogue.
Two recent stamps of Gibraltar have had a sensational rise in value. These were the 4s black and carmine, and 8s purple and green of the King George series. Issued only in 1924, they were suddenly withdrawn in 1925 and promptly soared in value on the stamp market. The 4s. is now worth £2 5s., and the 8s. costs £8, showing a nice profit for those who got them through the new issue dealers at the time, at a small commission over the face value.
At the time of writing the four jubilee stamps 2d., 3d., 6d. and 1s. are in current use in the island, and two of them temporarily supplant the 2d. and 3d. in Captain Garrood's view design. The jubilees are to be kept in use to the end of the present year. Meanwhile the 1d. scarlet and 1½. red-brown view stamps are the denominations in chief use. The view stamps are in keeping with the present policy of the colony in advertising itself in its peaceful aspect. Long regarded as the naval key of the Mediterranean we find on letters nowadays the slogan postmark "Gibraltar - the Travel key of the Mediterranean." The stamp design scarcely suggests the stark majesty of the Rock, but it was intended to call attention to the colony's attractions in peace rather than in war.
More about the author
Frederick John Melville (1882–1940) was a British philatelist, prolific philatelic author and founder of The Junior Philatelic Society. He was also a founder in 1907 of the Philatelic Literature Society. Melville is a member of the American Philatelic Society's Hall of Fame and was a signatory to The Roll of Distinguished Philatelists in 1921. ~ From Fred Melville on Wikipedia.
he Australian penny red KGV Head was first issued in 1914 and quickly became one of the most studied stamps on the planet. After 99 years collectors thought the issue had no more secrets – that myth was destroyed only a few short months ago.
In early 2013 a Gentleman in Scotland discovered an Australian 1d Red KGV stamp (cancelled 99 years ago in suburban Sydney) which now plays a significant part in philatelic history.
The Australian 1d red stamp with the King George 5th portrait is the most popular Australian stamp collected in Australia and overseas. What aspect of this stamp placed it on ‘page 1’ in the world philatelic press; it was not its condition which is clear to any potential buyer, but rather the suggestion that the stamp has a “sideways watermark”. If correct this was a new discovery and a unique item of Australia’s most popular stamp.
Thankfully the stamp was given to Mr. Ian Perry a leading Stamp Dealer in England who specializes in ‘Australian Stamps’; to bring to the “Melbourne International” in May 2013 for examination by Drury and other leading philatelic experts.
Drury arranged with Mr. Neil Holland of ‘Scientific Document Researches P/L’ to use Mr. Holland’s scientific equipment. Drury and Holland have been friends for more than 20 years via their association in the Police in Australia, and both have a common interest in the prevention of fraud within the stamp collecting market in Australia.
Mr Holland is a professional of the highest ethical standing in the opinion of Drury but unfortunately not experienced in “1d red shade group identification” which was required for correct stamp classification upon the certificate. This is the only reason as to why Mr Holland was not invited to also sign the certificate. The 5 ‘signatories’ upon the certificate are all thankful to Mr. Holland for the free use of his equipment which played an invaluable part in their respective examinations.
After considered examination all agreed that the stamp was genuine; a ‘sideways watermark’ and a unique new discovery of Australia’s most popular collected stamp worldwide.
Drury chose the 4 'signatories' to also examine the stamp and sign the certificate in light of their outstanding philatelic achievements and well known ethical standing at an international level within the philatelic world. A short background of the ‘signatories’ upon the certificate;
1. Mr David Terrington.
Former President of the ‘Royal Philatelic Society of Victoria’ (RPSV).
30 plus years member of the RPSV.
Former member of the RPSV ‘Expert Committee’ (some 10 years).
Current and former member of the BSAP, ACCC and many other Clubs for some 40 years.
Received a “Gold” medal at ‘Melbourne International 2013’ for his display of the Australian 1d stamp of KGV.
In the opinion of Drury, Terrington’s 1d KGV collection is in the top 5 collections of its type in the world. He is considered a leading world authority in this area.
2. Mr George Henze.
It is with great sadness that we advise that ‘Dear George’ passed away in July 2013 at the very young age of 49. His continued free work and friendship to many within the ‘philatelic world’ is and will be missed by so many at an international level.
Vice President of the ‘Australian Commonwealth Collector Club’ (ACCC) and member for some 20 years plus.
Current and former member of the RPSV, BSAP and many other Clubs.
In the opinion of Drury, George was in the top 5 experts in the world on ‘colour’ and ‘variety’ identification of the Australian KGV 1d red stamp.
3. Dr Scott Starling.
ACCC Committee member and ACCC member for several years.
Considered by Drury as a rising star with a bright future in Australian philately, and is further supported by Drury in that Dr Starling also issues his own ‘certificates’ in light of his on-going research of the Australian KGV series of stamps.
4. Mr Geoff Wotherspoon.
30 year plus member of the ACCC, member of the BSAP and many other Philatelic clubs.
In 2010 he was the 1st to plate the KGV 4d “Temple Flaw” as 1L40.
He is considered perhaps the world authority on the KGV 4d value in the view of Drury.
He is an acknowledged outstanding expert across the KGV Australian stamp series with emphasis upon the 1d value.
His outstanding quality control in philatelic research continues as he solves the last remaining areas of mystery for many of the rare flaws of the 4d value including the 4d violet ‘line through value’.
5. Mr Michael Drury.
Former President of the ACCC and current Committee Member. (30 plus years member).
Current & former member of the RPSV, BSAP and other Clubs.
Regular contributor to the Australian Commonwealth Specialist Catalogues.
In 1989 after approval from Buckingham Palace, Mr Charles Goodwin, ‘Keeper of the Royal Collection’ brought part of the ‘Royal Collection’ to Australia for examination and free certification by Drury. This is the 1st time that approval had been given for part of the ‘Royal Collection’ to leave the UK for private research.
Over the past 25 plus years Drury has issued many hundreds of free certificates for Institutional collections within Australia Post, the Powerhouse Museum Sydney, to many leading Auction Houses and Dealers/Collectors around the world in his on-going research of the Australian KGV ‘side face’ series of stamps, with emphasis upon the 1d red value and the ‘Salmon Eosin’ shade.
It was with eager excitement that the above group examined the 1d red KGV suggested ‘sideways watermark’ with the free professional support of Mr Neil Holland and his scientific equipment. In being part of ‘philatelic history in the making’ they each signed the Certificate, given free to Mr Ian Perry who in turn agreed to donate 50 pounds to his favourite Charity in the UK.
This is the 21st Century and as such a ready accessed image of the face and rear of the stamp into the next millennium will always be available to all (several computer sites and books) along with many detailed comments with respect to condition etc. Any future attempt to fraudulently improve the stamp will be detected by the well-knowledged international philatelic trade and collecting fraternity.
To the lucky (International Level) Philatelist who successfully buys the stamp from the upcoming Phoenix Auction in Melbourne on the 26.10.2013, please protect this unique treasure with pride; as to the accompanying ‘free certificate of expertisation’, that can be destroyed if considered worthless.
My thanks go to Dr Scott Starling who gave me kind permission to reproduce his article here.
