M 41 greatcoat for enlisted men, maker marked

Hard worn example of M 41 greatcoat for enlisted men, maker marked, and year is practically invisible, dated 41, but we are not sure, the first digit is for sure 4, the second is unclear but looks like 1. The coat has some rips and nips which are visible on the pictures. The overcoat have M 43 insignia and very nice shoulder straps. The shoulder boards are fashioned and inside is something hard like a cardboard. Handmade aluminum artillery emblems- crossed guns attached with thread, and two rank stripes of junior sergeant made from a piece of lend lease ration can. The buttons in the collar tabs are M40, and white coated, the collar tabs made of baize, which in our opinion made this coat more interesting, due of the baize tabs and shoulder straps are earlier and rarest than wool. Size is big. Very nice addition to any ww2 soviet collection!
