This is an older Selmer Paris bass clarinet mouthpiece with cap and ligature. The piece was possibly worked on in the past and does not show a face stamp anywhere on the table or on the side of the body. It measures .065"/ 1.65 mm.
The physical body of the piece is in very good condition showing some typical cosmetic character. Its shank is also in great shape. Ships with non original metal cap and ligature set.
