Not my horn.
Eb Champion Helicon. 3v. Interesting wrap.
Anyone brought one of these Champion (or similar Ditson, Lyon and Healy) back to life?
How’s the sound pitch and tuning?
I don’t have specs but recall fairly small bore, small tuba receiver.
Eb 3 valve could be workable as is. Looks like room for 4th.
