The back of this photograph is reproduced below showing signatures of the men in the picture. We thought it would be an interesting project to try to identify all the men and what happened to them. As you can see they are mostly initials and surnames so the first step was to try to identify their full names. Which we managed to do. We don't expect to be able to put names to the faces - but if we get lucky we might be able to do that for the odd one or two. 

Here are the names in the order they appear on the postcard, with their Service Numbers. Dad hasn't signed the card and his service number was 621812. As you might have expected all of the service numbers are fairly close to each other.

Two of these men died during the war, both when their bombers were shot down over Germany. The remainder survived the war.
