Berg Larsen 100 0 M Tenor Saxophone Mouthpiece
Vintage Berg Larsen Tenor Saxophone Mouthpiece. Marked 100 0 M and tip opening measures true at .100. Looks like the table / facing may have been cleaned up by a refacer at some point. The table looks like it had the denim machine marks and the M is slightly offset. Some wear from teeth in the bite plate.
