Did it exist? My list of base workshops from 1945 jumps from 23 to 32.
There is a 25 Command Workshop listed based at Lanark Scotland.
If it was during wartime I would think it would be very hard to find for obvious reasons.
Here's a quote by Steve Madden, from September 25, 2014:
The "E" is indicative of Eastern Command workshops, and auxiliary ones at that..........the equivalent of "B" vehicle auxiliary workshops in the UK........these were numerous, many in civilian garages and workshops, and it was the same in the Middle East during WW2 and into the post-war period..........with the Middle East encompassing a huge area perhaps larger than the UK, workshops were extensive and many a back-street premises in Cairo, Alexandria, Palestine, etc, were involved........
No Idea on the "D", "C", marking, etc, but may have indicated a particular sector or rebuild classification .............
As for other workshops, "Base" workshops were generally Middle-Eastern based (huge Ordnance depots) and "Command" workshops were generally of similar size but located in the UK and Europe.................they were the senior to "B" and "E" auxiliary workshops..............
Thanks Steve! If you ever figure out what the C at the end of the serial number is, would you please post.
I was referring in my original post to the "C" SERIAL (tank) number, nothing else.......
All WD Ariel's had the "XG" frame number prefix........engines had the "BH" prefix.......
"AS" is normally a mark for "Army Spare".........
Some Naval contract W/NG's had an "N" before the engine number (eg - "NBH 12345")........and some Air Ministry (RAF) Contracts had the engine number prefixed by an "R" (eg - "RBH 12345").............
John T, REME museum best source for workshop info but they are currently within a move from Arborfield to the former RAF Lyneham.............
