From the RAF PoW index I've located the 3 Canadians, but Stuart as an American isn't recorded. He may still have been at Luft 3 with a similar number...
Camp PoW No
L3 2621 Hovey C Y J/17106 RCAF
L3 2616 Hastings G V J/17665 RCAF
L3 2624 Lockhart I A L J/18450 RCAF
Note that Hovey is shown as C Y, not C V.
There was an eminent C Y Hovey in the mid fifties involved in some learned research on insects.... could be one and the same. (I didn't follow up because I was looking for a CV Hovey, but noted the similarity.....
Also Lockhart is shown as I A L, not J A L, but it was JAL on the Loss Card so it may just be a transcription error, or we need to look for an Ian or Isaac or similar!
Now to crack the other side of the pond!
Over to our Canadian friends...
The 434 Squadron Association have been contacted but no luck thus far....
