Hi,
I have been going through his AIR76 and his post war service. As far as WW1 is concerned he served with three squadrons 16/10/17 103 Sqn, who were based at Serny during his term with the squadron 10/12/17.
109 Sqn on DH9’s were a home based wireless squadron and 13/07/19 with 244 Sqn who served in Ireland.
Looking at the Photo, I would discount 109 and 244. Presumably the photo is of his time with 103?
