7/29/19 - This is an original WW1 Luger magazine. The magazine has an aluminum frame and a wood base. The base is in excellent condition with a serial number stamp "9972 l" There's no imperial or Erfurt proof stamp though, meaning this could have been for a commercial or police gun. The frame has surface oxidation on both sides but no pitting. Wood base is in great condition. Strong, fully functional spring.
