Hi everyone, I recently bought this Volkspolizei jacket for a meister of the volkspolizei (maked "O" for 1974, if I’ve understood correctly), but I’m a bit confused: Why this jacket has not the "schutzpolizei" arm patch and the service chevrons on the left sleeve? Wasn’t that the standard for every meister ranks?

Also, what medals should i put on?
