The Remington shank or stem is similar to the standard large shank trombone mouthpiece, The difference is the rate of taper. A modern large shank mouthpieces has a Morse taper .050" rise per inch length and the Remington style shanks have a taper similar to the Brown and Sharp taper .04167" rise per inch length.

Remington shanks were used in many vintage Conn large bore trombones starting in Elkhart, (1954-70) to Abilene, TX (1970-86) to Eastlake, OH (1986-92) Conn 8H, 88H, 60H, 62H, 70H-73H from around 1954 until the early 90’s. PLEASE NOTE the modern Generation II 8H and 88H trombones use the standard large shank Morse taper mouthpiece offered on our website, not a Remington shank.

Why does it matter?
A standard Morse taper mouthpiece will not seat properly in a Remington receiver, it leaves a gap around the end of the shank which has a bad acoustic effect, this may cause bad slotting and for some notes to not speak as well as they should. A good rule is if it wobbles it’s probably the wrong shank.

Just to make it a little more confusing the Conn Generation II 8H and 88H trombone with removable leadpipes (you know who you are if you have them) has one of the pipes labeled with an "R" - for those with Remington shank mouthpieces wanting the original shank on there modern Gen II horn.

Who was “Remington”?  Emory Brace Remington (1892–1971) was a trombonist and music teacher at the Eastman School of Music in Rochester, NY from 1922 until his death in 1971 His unique method made him one of the most well-known and influential trombone educators in history, his teaching and students from his tutelage still have a big influence of the sound of modern Orchestras today. He was also a member of the Rochester Philharmonic Orchestra from 1923 to 1949. In 1954, Remington completed work with C.G. Conn Ltd. in developing the 88H tenor trombone one of the notable changes was a bit larger shank with a slightly different taper for its acoustic properties.
