Hello, was it common back in the 1940 `s for musicians to use an alto sax mouthpiece on a Tenor. A coworker brought in an old Tenor sax and asked me to play it. after i played it i noticed the mouthpiece was a Berg larsen duckbill stainless steel. I went online to learn more about this mouthpiece and found out this was actually an Alto mouthpiece. Thank you Joe in N.H.
