6/4/18 - This is an original WW2 production, 1940 dated MP 40 magazine. The magazine has some spotty wear throughout, mostly light rust spots and discoloration. Most of the bluing is in tact though, and the spring is strong and fully functional. The spine of the magazine is maker stamped with a "122" code and is also 1940 dated with waffen proof stamps. Guaranteed original.
