Iron cross 1st class by C.F. Zimmermann, Pforzheim. Three piece construction with magnetic, iron core and soldered on setup. Maker marked with the PK code of Zimmermann "20" and the LDO code "L/52" on the backside of the needle. Very good condition with almost all the paint remaining on the core. The very nice and matching Zimmermann box with push-button opens and closes correctly. No repairs, no damage.

Beautiful set with not often found double Zimmermann maker mark underneath the pin!!
