Thanks for the input guys and from the H&H advertising, I too would guess it notes H&H type locks. Regarding ole Otto Reif, I can't seem to find exactly what he was doing from 1934 to WWII. He did register a firm but I do not know it's function for now. With his used car salesman talent he was able to capitalize on the situation post WWII. I would like to clarify that all of his frames I have seen wear Simson touchmarks but not all the tubesets.

Kind Regards,

Raimey
