Martin Top-Action 4 Rotor

[Paul Scott]

It's not just you, Harv! I enjoy playing good sousaphones and especially GREAT Martin sousaphones. I also enjoy my Conn 40K.

Leave it as it is!!! check the valve alignment and check the vales for leakage. The Horn is very cool ( you beat me on Ebay for it ) I have seen 3 other martin rotary valve horns all front action but with the valves turned like this one. The engraving is consistant with horns of the era. Many of the big horns had sparse engraving. I have never seen a Big Martin with detailed engraving. Although the valves look like Cerveny valves I was told that Martin did indeed make the rotary valves for these horns. The horns never were very well accepted and never went into full production. the lack of balls in the lower register is a trait common to the other rotary Martins I have played. I belive Mike lynch has one.
