I've got a Selmer glass mouthpiece that came with a Vintage 1936 King Voll-True II Eb Alto Sax. The mouthpiece has Selmer in cursive writing and a capital B proceeds the signature. Can anybody help me place this and give me a ball park on what it's worth? Thanks.
Secondly, I have a Equa-True King 'A' mouthpiece. Anybody know if it's worth anything? Thanks.
