This is a Carlsbad vintage Brilhart Ebolin series mouthpiece for the tenor sax. Originally a 5 or 6 digit serial number, only the first digits are visible due to wear, # 3119. This is a true Carlsbad, CA, vintage piece. It is stamped a 3 and measures similar to a modern 5* at .083”. The piece shows ligature scratches around its body but those are purely cosmetic, and there are no cracks or chips anywhere. The original white bite plate has no teeth wear or indentations, and the original tip and rails are in perfect shape.
