Wiki’s picture from Kentucky RZM “Erlaubnis” correspondence stamp.
Has anyone ever seen this stamp on the cello sweat shield in this posture before?
As some of you know, I have spent a fair time with the RZM data, and my understanding is this stamp was for correspondence
from a licensed maker with the RZM to ease the paper work in Munich. That is, it was intended to stamp correspondence,
not to be an RZM tag of the kind found in textiles.
I have seen it used once as an RZM tag, in fact, in a piece I own I got in the early 1970s.
I have never seen this stamp used in what I deemed to be an authentic cap.
Any other examples you might have I would love to see, so I may assess my own thoughts.
