Nsdap Party Badges

[JWYATT]

Does anyone know or have an opinion what year the party badge/pin came into its final design?

I believe the basic NSDAP pin was designed in 1921 by Hitler himself and remained relatively unchanged until 1945.

The smaller details (like round "O" and swastika touching the inner rim of the silver border of the red) were standardized across all manufacturers by the RZM in late 1934.
