Middle Logo R.M. R. Malerne Paris Hard rubber clarinet mouthpiece Chedeville

Description

This is a nice example of one of these pieces
R. Marlene made some good pieces in the day back when they were hi g chedeville blanks which I believe this one to be. I cannot find any markings like qualite superieure or anything else, however it does seem like a good ched blank
See pictures for reference to the condition
seems to be in pretty good condition
