3/23/20 - This is an original late WW2 variation P.38 magazine. The left side of the frame is stamped "P.38v U". The U stands for unhardened metal which was a late-war manufacturing technique used to speed production. There are no other markings. The spring is excellent and fully functional. The original blued finish has minor wear and a small are of pitting at the P.38 stamp. These magazines were issued with late WW2 production P.38 pistols.
