The RAMC number that ShaunJ has quoted, i.e. 7254869, is a post war service number. Seven digit service numbers were introduced in 1920. This would suggest that his service record has survived and is with the Ministry of Defence. Such records are being handed over to the National Archives to be digitised and (eventually) put online (probably via Ancestry).
Just to clarify...
There were no such things as "Service Numbers" in the British Army. From the 18th Century to 1920 they were Regimental Numbers as they were admin'd by the regt and given a number by them on enlistment.
In 1920, Army Order 338 decreed the use of the term "Army Number" and block allocations of numbers were given to the Regt and Corps.
During Regt Numbers you could get up to 100 with the same number.
The 1916 attempt to rationalise the Territorial Numbers failed.
So Army Numbers with block allocations came in.
Sadly there were still repetitions.
There is no period documentation that uses the term "Service Number" form 1800 through to ...at least ...1950...And Im sure I was given docs with the term "Army Number" and not Service...I need to dig through the paperwork!"
It changed for me as I got an "Officers Number" a bit later on after being in the ranks.
