SA/NSDAP/HJ/SS Visor cap eagle
This type of eagle is not specific to one single branch. These are mostly seen on SA Kepis and HJ Leader visors. NSDAP is also an option, although they mainly wore the gilt version after 1938. You will even find them on SS visors on occasion. There are period photos that will show this type of eagle for all of the above.
Maker marked RZM M1/151, which means it was manufactured by Franz Jungwirth, Vienna.
Eagle is made of aluminium
Excellent condition, look a lot better in hand. Note that the silver color is perfectly even on the entire front.
