Mouthpiece tests for the Besson 2056 4V Compensating Baritone
Remington Shank is not quite the same as "eruo" or medium shank, but close. It is quite a bit larger than just a bit different taper compared with a Bach tenor shank. The Conn 88H's and the Conn Connstellation euphonium both used Remington shank. I have a couple of the mouthpieces, including a very nice Conn 3 with gold plating. Definitely does not fit into a tenor shank horn. The medium shank mouthpieces (Wick, etc.) will fit into my Connsteallation, however.
