Its an Eb sousaphone. Judging by the ferrules on the slides, I'd say its a York. The used that design to theoretically avoid any 'steps' if the tubing didn't come together perfectly. My 1906 horn doesn't have them, but my 1918 does. Nothing amazing but interesting that no York engraving is on it. Perhaps a custom order by Robert Martel? Anyone every hear of a player by that name?
