For who was interested a few weeks ago...
Dr Marzan had a line of tubas produced for a short period of time in the 60's or 70's I believe. They were under the DEG lable from the factory in Geneva, WI. There was a 4-Rotor CC (Which he considers only 2nd to his Sander), a 4-Rotor BBb, a 4-piston 1-rotor, A 5-rotor, and a euphonium with innovative compensation for those tuning issues. All the Tubas were compensating.
I hope that helped. Any more questions and I'll ask the great one.
