This is a Great Neck, NY, vintage Brilhart Ebolin series mouthpiece for the tenor sax, serial number 38810. This piece is an original 4*, with tip measuring .085” (comparable to a modern 5*). Much of the original factory stamping has faded with time, but the piece is excellent physical condition. There are no deep indentations in the original white bite plate, and the tip and rails are flawless. This piece comes in its original box, with matching serial number on it.
