This is a vintage Brilhart Hard Rubber mouthpiece for the alto, serial number 176929. This piece is stamped a 2 and measures .066". It is in excellent physical condition with no major wear to speak of. There are no major scratches, the bite plate hardly has a mark on it, and gold lettering still looks incredible as well. This mouthpiece was well taken care of, as the tip, rails, and baffle all look like new.
