This is an hard to come by 1940's vintage Berg Larsen slant signature Duck Bill, marked 85 on the shank. The Berg is in great shape and features the classic bullet chamber configuration. The facing profile of the piece around the table, tip and side rails is in pristine original condition. The tip does measure a little bit more open at .090”.
This mouthpiece came through the Saxquest shop in 2014. It is not as pretty as some of the pieces listed in the museum but it is in great shape for its vintage and a very killin' player. It is nice and free blowing with a big fat sound.
