Markus, if RZM 72 then Paul Cramer (M4/72 is Wilhelm Deumer)
It's political anyway, due to the RZM marking. Timeframe is about 1934, as
when it would have been marked M5 (for "Uniform-Effekten") it would have
been 1935 and later, as from 1935 on the new indications went in force!
In a Paul Cramer cataloque are mentioned: 45 and 60 mm versions in yellow
and white (aluminum color) for SA, political leaders, Werkschar and NSKK.
In the beginning of their cataloque they mention what RZM permissions they
owned: RZM 1/114 ) Abzeichen); M4/44 (Koppelschlösser); M5/72/3 for
belt-accessoires for the HY and DJ (also they owned DRGM 1323713 for that);
buttons from Steinnuss G/4/86 and buttons for political leaders as G4/486 also.
