Henry Lehnert patented his Centennial ( for our nation’s 100th Anniversary...patent issue date Jan. 12, 1875) design for baritones and Eb tubas where the instrument was held by having it on both of your shoulders with your head in the middle and the bell being in front of you.
Louis Schreiber patented ( patent issue date May 7, 1867) his Tear Drop design ….which he made for all voices from Eb cornet down to Eb bass..that was teardrop in design and went over your left shoulder with the bell pointing up. It also had the world’s fanciest ‘spit valve’…an actual rotor used to empty out the condensation. Both Lehnert and Schreiber used string rotary action rotors for their instrument and they were made in brass and nickel silver….
