Strange marking? on NSDAP partei badge?

[German_military]

Hello,
I've got a question about this NSDAP Partei badge.

Why is it marked RZM and not with a number (M..../...) Is this possible?
It is marked Ges. Gesch 2 times.
The badge looks good, but I need some help on these markings.
Just to be sure.
greetings
Frank!

An early badge (1934-ish) could be marked like this.

Assmann RZM marks, for example, went:-

1933-4 .........'RZM A GesGesch'
1934.............'RZM 17'
1935.............'RZM M1/17'
