Kindly send any and all fotos to me & I'll gladly post them for you. For the most part, there were small merry bands of mechanics that did the heavy lifting for making weapons platforms. There were Systemmachers, Laufmachers, Schafters & Fahrrädermachers just to name a few. So if you fancied a gun or a bicycle, these guys more than likely played a part in the construction of said item. So in order to be paid & take responsibility for work, they applied a mark to the platform that pointed to them & likely wise they took compensation & liability. Therefore, each gun will wear mechanic marks.
