Hi
Thank you for your replies.
Aircraft Mechanic fits in well with his skills. He always mended things, had a bench and tools at home. I always thought he was in the army. In 1914 the RFC, I believe, was a branch of the army and that ties in nicely too. It would be nice to know what he did at the end of WW1 whether he left immediately of carried on working on aircraft for the, now, RAF. Maybe I'll find out one day.
Thanks again
Jim
