I Just bought an alto sax mpc "Martin Frères - Paris" on ebay but couldn't find any info on it. What I did find is a picture of an "Ad. Sax" alto mouthpiece wich looks the same to me.
Here the pics: http://uk.pg.photos.yahoo.com/ph/dje...nm=df5cre2.jpg
Can anyone tell me more about this mouthpiece!
