Jim, that has to be the most ridiculous thing I've ever heard. There were, in fact, a great deal of production guns with HAND-STAMPED markings. This is because, and keep with me here, there were places on earth where manpower was cheaper than machinery. China, for example. Trench guns had hand-stamped markings to signify acceptance by the U.S. Army Ordnance Department. WWI U.S. dog tags were hand-stamped, as well.
I'm not sure what prompted you to post this meaningless and trite morsel of BS, but please refrain from contributing to threads where you clearly have no information to provide. Note how Harley had the tact to simply state that he did not know anything about this gun. He noted there were similar guns in Zhuk, just not this exact model. That was contributing. That was informative. Your post delves beyond the uninformative and into the rude.
