In going through my pile of mouthpieces bought or given to me I came across a Conn Gold-Tone mouthpiece featuring a cushioned rim similar to a Rudy Muck. The Conn Loyalist has the following description on its web site:
Gold-Tone mouthpieces are known to have existed for cornet, trumpet and trombone. For cornet I have come across numbers 22, 25 and 26. For trumpet I have seen a 25 and a 26. The 25 is a (very) small cup diameter mouthpiece with a wide rim, the 26 has a somewhat larger diameter cup than the 25. At least one model of the trombone "Gold-Tone" was the number 21 "with deep cup, was typical of the full line of small brass mouthpieces in this styling." Gold-Tone mouthpieces are very rare.
I have found a picture of Benny Carter holding a Conn trumpet (recognizable by the straight braces, looks like probably a 22B) with a Gold-Tone mouthpiece, and Henry Wells playing trombone with a Gold-Tone mouthpiece.
The two pictures below are from the site and listed as a Conn 26. Mine is the Conn 21. Any further information would be extremely helpful. I know this is a tuba/euphonium site, so the hook is that it came attached to an old Holton Collegiate baritone in questionable repair.
