Possibly early 1900’s or late 1800’s Classical Trombone Mouthpiece
I actually rescued this mouthpiece from a pile that were going to be scrapped, and boy what a find! A little polish and a great background shot for a future library is possibly born.
Some consultation with a more experienced individual points towards this mouthpiece being based on the sort of mouthpiece measurements one might find from the Classical period- large, relatively flat rim, smallish cup, somewhat sharp transition into backbore, small bore.
