UBB.threads Forums Edged Weapons Army, Navy, and Luftwaffe Forum 1945 1st Luft "Field Day"

I think I may have seen two of these in all the years I've been collecting. I've never heard of any repros. This is certainly an exelent example though.
I've always wondered why there were no 1946, '47, '48 Field Day daggers. Why only for '45?
