Ed,
Numbers on 36 pattern daggers are not often seen but they appear from time to time.
It might be a 33 dagger in a 36 scabbard. Pictures would be helpful to determine that.

The number 1232 goes to a Werner Thoms,
Born 07.05.1899
NSDAP number 91514
SS-Haptsturmfuhrer 20.04.1939

Good luck and hope it turns out to be his dagger,
Please try to post pictures for the rest of us to see!

Cheers

Emil
