....sorry, sent it prematurely
His first tour of operations would probably have ended in 1944, given that he'd been on active service since the Summer of 1942. As I say I am pretty sure that the coincidence of Duncan Smith mentioning a Sergeant Hulse of 93 Squadron in May 1944 seems too close to avoid making a strong case for this being Graham Hulse. I know Chris Shores doesn't mention this is Hulse's biography but...
best regards
