Original German WWII Cased 1939 Iron Cross First Class Double Hallmarked “L/52, 20” By C.F. Zimmermann- A very nice Iron Cross First Class with standard Zimmermann pin and double proof marks, “L/52” and “20”. The front the Iron Cross is typical for the maker with the correct “1939” font and other quality features we expect to see from Zimmermann. There is some nice age tarnishing, with about 95% of the original silvering still present. There are some very small rust spots on the paint, but overall, the paint retention is approximately 95%. The center of the Iron Cross is magnetic. On the back it still retains most of the silver frosting and from most likely being inside the case. On the inside of the pin the double proof version of the Zimmermann firm’s mark, with the “L/52” within a recessed stamping, and the number “20” are near the bottom of the pin near the hinge. The black case has the with silver Iron Cross imprint on top of a lid, with push button. It is an early version with some slight wear & tear. The hinge does not close perfectly, but open & closes just fine. A very nice set!
