Hi Pam & Ken,
And thank you for your interest.
My Uncle's full name was George Felix Wilson, DOB 19/2/1900.
The Record details were downloaded from The National Archives Site, via the on-line Catalogue, REF:
ADM/339/1 Image Reference: 57414.
I can't post the download here because of Copyright, but it just consists of two index cards, one with his DOB, next of kin & address, details of height & colouring, - that he can swim(!) & Occupation, (Grammar School Boy). The other card has the Battalion details & numbers that I've posted.
I'm guessing that the rest of his records, (relating to the RFC) will be at Kew on microfiche, in AIR76, but I haven't found them yet. I wonder if he would have retained the same Service Number, Wales Z/2065?
Romilly.
