I did think this was taken on leave. It seemed to be a photo of men from one area of Kildare, there are several different cap badges but maybe as you suggest that's because it's a group of POWs.
They are just standing in front of a hedge, only one is named and he's also from Kildare.
Oh well,
He's one of quite a few Grand Uncles, so not sure if I want to spend £30 on him, maybe when the recession is over, but thank you very much for the information.
You're second post came in as I was typing, now that is interesting as I know he contracted TB while he was a POW.
If I could just find out if this Daniel was from Kildare I'd have it. The number matches the record I found btw
