Does anyone know anything about the Walt Zeiss Tubas that I was told were manufactured by Cerveny up to the 1970's. I heard Dale Phelps say his BB-Flat had a very large .890 bore and he spoke highly of them. Please tell me the basic details of how long they were produced and are there many used ones out there?
