7/26/17 - This is an original WW2 era production replacement code Mauser Luger magazine. Mauser stamped their field replacement magazines "42" on the base. This magazine has that specialization, but there is also what appears to be a post-factory serial number stamp. This is a fairly minor offense, as these magazines were made to be re-issued and numbered to a new gun. The other minor offense on this magazine is the condition. There is light surface wear and surface scratches particularly on the spine. Priced accordingly. Fully functional and guaranteed original.
