Proof Marks On Commercial DWM

[Mike K.]

Hi John,

First, thank you for your thoughtfulness.

I have attached additional images. This is a recent shooter purchase at a gun show from a vendor who was not sure about the history. I simply believe it is a mismatch. The upper receiver was force serial numbered to the lower. Only the trigger, safety bar, safety lever, and lower receiver match in number. The take down lever and side-plate are mismatched. The toggle, toggle link, and breech-block match. The firing pin is unnumbered. And, the hold open lever is unnumbered as well. Looks like both the upper and lower frame had metal reworking. I paid commensurate to the condition, simply for a shooter. Thanks to those forum members with supportive comments and opinions.
