Yes, with relation to the reverse markings as well as the RZM logo, explained on many pages in The Party Badge book. BUT..... the research pertains only to small official badges, not belt buckles, Helmets, Cloth or anything else.Joe have you narrowed down the time frame to when the RZM took hold.
They used the same Boerger HJ (thin swastika) diamond for the article as well :swissInteresting badge due to the very thin swastika. I've noticed on many fakes the swastika is very thick and odd looking for some reason.
