I might be able to help a little here until Johnny V. has time to take some more pictures. Here are the two knives shown closer in a side by side from one of his images. I think that it shows some of what he is making reference to.

Also in looking at it in a direct side by side image my sense of it is that the pommel on the the Puma might be a higher grade alloy. Possibly from Durener Metallwerke which made period aircraft grade materials. Not so for the �DJ� version of the knife in any of its many assorted incarnations. I also am probably going to revamp my �theory� some, but don�t know at the moment just what shape it will take. Although I think it�s fair to say that I think I�m seeing a lot more in the way of postwar activity. FP
