Iron Cross 1'st Class 1939 Maker Marked

Three piece construction with magnetic (Iron) core. The black paint is intact to about 95%. Reverse is complete with hinge, pin and catch. The pin is maker mark stamp but it’s hard to read. The cross has a gap between the frames at the 3 o clock arm, see pictures. The cross shows a nice age patina all over and is in good still used condition.
