Below are examples of RZM ( Reichszeugmeisterei der NSDAP ) codes used by the Germans and instituted in 1936 on political daggers in place of maker marks. The military organisations did not come under control of the NSDAP and so retained individual manufacturers trademarks. The RZM / makers stamps below shown in the top section are known transitional markings used during the crossover period from makers marks to RZM codes, ( SHOWN IN WHITE ). The lower section reflects the recognised known SA dagger makers from the years 1938-1942, ( SHOWN IN RED ). Although the known list of M7/ designated dagger manufacturers codes is extensive, not all are observed producing the RZM marked SA dagger. Also be aware that many manufacturers changed the appearance of their individual RZM stamp from year to year, so although these marks can be used as a guide they cannot be relied upon to determine dagger authenticity.
