Hi Mark,
I went to the above posted, Dutch Archive website and did a search (zoek) for Hengelo...
There were a few more 1CACR goup photos and what certainly looks like "liberation" celebrations! There was one photo of an 1CACR officer, I think it is A/Maj. Copley, OC of B Squadron. I'll need to investigate a little more thoroughly... but later, I really should get back to work.
Always fun to discover new stuff though.
Bill.
