A mention of the Stomperud sold on gun broker and maybe was purchased by a Nazi memorabilia collector could be correct.

We had a garage sale a few weeks ago and I had an old WWII bayonet for sale. I picked it up at one of the many gun shows my father and I went to when I was little, most of them private affairs. There were no markings on the outside of the bayonet but on the inside of the handles was the same proof markings as on the Stomperud. I wanted $2 for the bayonet and a little old German lady gave me $50. Go figure.
