I originally said "I believe" the peened pommel would put in the WW II era, if I knew that for a fact, I would have said so.
After looking at Wiki, it stated that the "peened" pommel was the first design, later replaced with a "pinned"pommel, that reaffirmed what I felt was correct.
There is probably more information there than I could type to respond to your questions, hence my suggestion that you take a look.
Ralph.
