Hi
Restoration aside, I met Art a number of times long ago and am sure he'd be approachable. MM winner for shooting Panthers. 1H has a gunnery trophy named after him.
I discovered that he was a pre-war RC Dragoon and passed some nice mounted photos onto the Regiment one time.
I once asked him about Le Mesnil-Patry. He said "Yeah, we walked back from that."
regards
Darrell
