This is a NSDAP Parteiabzeichen (transitional period), marked RZM 62 (maker Gustav Hähl).
The condition is used, there is some funky discoloring in the white enamel.
However, this is a very rare badge to find. The RZM 62 mark WITHOUT the M1 part is only the first i’ve seen of this maker. Despite the condition very rare!
Period 1933-1934 (my guess is early transitional period, by 1935 they must have had the M1 marking included in the design, here it isnt!).
