Bell: 20in Height: 37in Displayed courtesy of Phils Rugs and Relics (http://www.rugs-n-relics.com). Now, to add a little confusion. Upon further review of the Conn Loyalist, it appears that the 20J was a three valved horn, but the 24J and the 25J were 4 valvers. However, their dates of manufacture were suppose to start in 1924. Only the serial number of the following horn places it at 1919. Update: Apparently, the model# for the New Wonder Eb tuba was 20J for Front action, and 18J for the top action. A catalog refers to it as "New Invention Giant or Contra Eb Basses" 3 valves $145, 4 Valves $157!
