Thanks Rob. I just wish I knew the source of the "KAL. 16" or "CAL. 16"?? I don't think it is "FK" as F.A. Klett, tube maker, expired just before WWI and the company was owned by Frau Hedwig & Alfred Hauche. Some give 1927 as the year Emil Klett just may have received his master's brief, although it could have been a few years earlier. He also was a tube maker and more than likely embraced mechanization. I may sound like a broken record but I think it is a valid point, but mid 19th century there were no less that a baker's dozen of Klett gunsmiths, most masters, was well as the odd bayonet maker. There is a Klett gunmaker today, but not in Suhl so pretty much WWII decimated the Klett ranks. With the Krupp tube steel type stamp, I'd say the S&S in a oval is for Sauer but the "KAL. 16" makes me pause but I guess there's no reason to think otherwise.

Kind Regards,

Raimey
