Hello Chris
On spreadsheets I have lists of censor types 2, 3 and 7 in my Egypt and Palestine collection.
175 items of type2, 729 of 3 and 78 of type7, all with postmark date, destination and name/unit of the censoring officer (where legible). 
No pics but given time to complete current projects I could then make a start.
Within a database spreadsheet I believe it is possible to include a thumbnail of the cover.
Regards
Graham

Hello
Looking at my copy of Frank Daniel's book I see no mention of the Ayrshire Yeomanry against censor 3/3870, neither is there any note of that unit on Frank's worksheets, only HMIS Dufferin.

Hello Mike
The "Hostile Countries Censor" was a title that became redundant in late December 1914.  It was renamed "PW Branch" of the censorship.
Censorship began in August 1914 in Post Office premises, but the "Neutral Countries" censors moved to Salisbury House. on London Wall, in September, leaving the "Hostile Countries" censors in King Edward's Building until they also moved to Salisbury House in November.
The marking directing mail to the "Hostile Countries Censor at Salisbury House" continued in use after the change of name, and after the PW Branch moved to Strand House in Carey Street in early 1916, and I have only recorded it used on mail from South Africa.  I therefore conclude it was applied in S Africa, not in Britain.
The removal of stamps from PoW mail was normal practice in Britain to frustrate attempts to pass messages under the stamps.
Note:  mail from camps in Britain often has postage stamps but they were applied by the camp authorities after the sender had handed over his penny and  the letter had been examined.
Best regards, Graham

Hello Tony
I put an article in the Wreck & Crash Mail Soc journal "La Catastrophe" some years ago, after examining a good number of covers ex Kingstonian.  I cannot find it on my current PC but I expect it will be on one of a large number of old discs from a previous machine.  I will have a search.
The point of my article was to identify where the different "damaged" or "salved" cachets were applied.
Best regards
Graham

Hello Tony
This looks like a mail box facility.  Some companies set up a service whereby their customers could use such an address and according to the customer's wishes the mail could be held or forwarded. 
The CCSG had an article back in 2013 which can be accessed in the Global Philatelic Library through the RPSL website.
Dennis Rosser & Graham Mark "WWII - GB - British Monomarks Ltd"  vol.40, No.3, p.86.
Unfortunately the illustration which accompanied the text is not too clear.
In this article reference is made to earlier articles which included questions about the mode of address, with examples used in wartime with and without censorship.
I hope this helps
Graham

Hello Tony
I have a book !!
Taylor, Revd Gordon (1978) "The Sea Chaplains", pub Oxford Illust Press, 603+xixpp. ISBN 0902280562
Beside a list of 13 columns of "Chaplains mentioned by name" in the the 43pp index, there are 12 appendices:
1.  Chaplains of Capital Ships during WW2
2.  Chaplains of the Fleet and Principal Chaplains
3.  Chaplains noticed before 1626
4.  ditto 1626-1684
5.  ditto 1685-1903
6.  ditto 1904-1978 inc temp Chaplains RNVR 39-47 & Chaplains RNVR mobilised in 1939
7.  Church of Scotland & Free Church Chaplains
8.  Roman Catholic Chaplains
9.  Chaplains RNVR & RNR (all denominations) RNVR 1917-58 & Chaplains RNR from 1958
10. Honorary Chaplains RNVR & RNR
11. Former Naval Chaplains who became bishops
12. Naval Chaplains known killed, lost or died afloat or on active service (from 1553-1945)
Unfortunately the lists of Chaplains in these appendices are not listed alphabetically, but by year and presumably then by date of appointment.

This source should add a few to your list.
If you just happen to be planning to be at Hinckley meeting I will bring the book.
Best regards
Graham

Hello Geoff
I cannot add more.  Ascheer's response tells it all.
I do have two or three examples of this handstamp used on mail.
Best regards
Graham

Hello Robert
This handstamp was listed and illustrated in my 2000 book on British Censorship of Civil Mails during WWI (2nd impression copies still available from me: £20 + p&p)
The handstamp reads CONTRARY TO REGULATIONS / Letters for Prisoners of War / must be addressed in ink.
This was a requirement originally laid down by the German Govt.
I had recorded only two examples back in 2000 but I have seen a few more since, so I would rate the marking as fairly uncommon.

Hello Ross
The official "Military Ops, Egypt & Palestine" (Falls Vol.2, part II) at p418 talks of the re-organisation of the infantry divisions in the Spring of 1918, when British battalions were replaced, mostly by Indian battalions but also by 1st Cape Corps, which became the junior battalion in 160 Brigade, 53 Div.
At p490 describing the Battle of Nablus, 18 Sept 1918, "... The Cape Corps then captured "Z" Hill by midnight and pushed forward to Square Hill which was found to be strongly held.  After a five minute bombardment it was taken at 4.45am on 19th ..."
No other mention in the book except in the Order of Battle in Appendix 3.
Graham

Hello Chris
I agree with Mike, not just every unit but also within units, I can provide, when you are ready, with a large number from Eg & Pal.  A good example of the multiplication is provided by the Devon Regt on garrison duties in Egypt - I think I have five or six cachets - some amended in ink for different companies as the regiment was split up with duties in various locations.
Best wishes
Graham

Hello Tony
No problem in getting my name wrong.  My father and grandfather also had reversible names.
The other ships you mention would not have had a contract for carrying mails.  My book "Imperial & Foreign Mails, sea Conveyance during War 1914-1918." on the lost and damaged mails was edited from PO records.
I suggest the attack in December was when the ship was eastbound and in February when westbound.  She was returning with Far East mails in February so six weeks between the two incidents seems reasonable.
Best regards
Graham

Hello Ross
The most likely ship that was carrying mails from Egypt was a French vessel "Ville de la Ciotat" Messageries Maritime, 6,390 tons, sunk by "U-34" torpedo 105 miles SW of Cape Matapan, on 24 Dec 1915.  81 lost.  She has sailed from the Far East and was also carrying mails from China, The Straits, Egypt and Cyprus.
Reference: "Imperial & Foreign Mails, Sea Conveyance during War 1914-1918" edited by me from PO Records, published by The Postal History Soc 1997, ISBN 0853770271.  In Jan 2017 I produced a Revised Appendix listing Outward Mails, Homeward Mails, both by date of mails, and Ships Alphabetically.  (A number of additions prompted the revision.)
A v small number of the books are still available at £15 (includes the Revised Appendix & p&p).  The Appendix alone is £3.50 inc p&p.

Hello Tony
A possible ship for this mail is the P&O "Sardinia", carrying mails from the Far East, India, Aden and Egypt.  Attacked by U-52 and damaged, 60 miles off Oran, 4 Feb 18, but she reached that port.
Post Office records give dates of the mail rather vaguely as Dec27-Jan.
Based on the date of the attack the ship would have left Bombay somewhere around 20 Jan so your cover could be dated early in that month.  Put a good light into the cover and you may be able to see the date without resorting to water treatment.
I can well imagine it could take a month to get the mail unloaded at Oran, shipped across to Marseilles then across France but NOT by the scheduled train service which was arranged to meet the P&O/Orient ships when they arrived.

For putting a light inside a cover I use something called "Worklight" -  it is an LED light, the box has a bar-code reference on it, but no name.  In my handwriting I have a slip "C O B LED magnetic work light".  It was only a few ££s on the internet.  The 'business end" is slim, only 5x15mm so it goes into a cover quite well without straining the paper.  It is rechargeable from a usb port.

Best regards
Graham

Hello Chris
In my 1895 Gazetteer there are three towns WEISSKIRCHEN (note double S)
A) in Austrian Bohemia on the left bank of the R Elbe, 20 miles N Prague
B) in Moravia 22 miles E by S Olmütz
C) in Hungary 47 miles E by N Belgrade.  Its Hungarian name Fehertemplom
If you are dealing with war against the Serbians 'C' seems the most likely.
There is no town listed with a single S.

Hello Peter
May I suggest that there was an enormous demand for postcards in Egypt in the first half of 1916 and I am sure that any and all available were sold or issued to soldiers.  With Divisions withdrawn from Gallipoli plus fresh Divisions sent from UK and from F&F there was a very large population of Tommys, Jocks, Taffys, Diggers etc. Just as in the Edwardian period in Britain you can find cards showing European and Asian scenes used domestically, I am certain I could find in my collections other "foreign" postcards used from Egypt.  If a transport ship had called at Corfu and then gone on to Egypt it would not surprise me if some enterprising purser had bought up a stock of picture postcards with a view to making a turn on his investment at Alex or Port Said.

Graham
