This one is way above my head. I'll adhere to a collector with more experience.

Regarding Steve's brass buckle, I don't see anything wrong with it. I had always considered these one-piece brass jobs to be private purchase pieces, but after reading Sleepwalker's comments, it does seem like the majority of these I have seen were in veteran's bring back groupings and if they were on a belt, it was almost always a private purchase belt. I really doubt they were being made for veteran's groups in 1919 when American soldiers would have been able to pick them up. These veteran groups, for the most part, were not formed until the 1920s, by which time the American army was gone. So, if they are not wartime pieces, then they would have to have been made for the postwar souvenir trade. Another thing to think about is that brass was a controlled metal during the war. The chances of some company getting this metal to make private belt buckles seems very remote. So, once again, the postwar explanation makes more sense.

Thanks Maxrsx, I've never seen these marks before. I wonder if anyone else has? Cheers, Richard.
