Why couldn't more instruments have thumb rings like these?
In my opinion these are worth trying to restore?
Hard to tell though.
If memory serves, a slightly older (wider wrap or shorter bell stack, medalion only had one year) i know of got restored, and was what i first got a chance to figure out eb fingerings on. Listening to others play it at the time, it had a glorious sound and none of the intonation issues i ran into trying to play it...
