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. The spine is stamped with "E/359" upside down near the top. There numbers "2466 j" are stamped on the bottom of the base that have been X'd out. The spring is excellent and fully functional. The original blued finish has minimal wear with no pitting or corrosion.
