C.G. Conn Elkhart Model 66H Large Bore Trombone c.1920s

One of my rarest large-bore tenor trombones is the 66H, which was produced from 1920 to 1925 before being discontinued. It features a .547” bore, making it a medium bass with a rotary valve to F and tuning in the bell. Similar to my 1939 Conn 66H (considered an 88H prototype), the bell section of this instrument is constructed from red brass, and its taper and size closely resemble those of the Conn 88H. Think of the 66H as the bell tuning variation of the 14H, as they were made around the same time!

Characteristically of its vintage, it has a traditional “flat wrap,” a friction fit connection, and a small diameter German made rotary valve. Notably, the slide of this trombone is unique in that it is the only Conn slide I’ve encountered with nickel silver outer tubes and a red brass end crook, perhaps a special order? Additionally, its width is comparable to a Bach 42, contributing to its distinctive blow and sound when compared to modern Conn trombones. It evokes the tonal qualities of German trombones, albeit with a more “American” vibe, suggesting that the original owner, likely a symphony trombonist from Europe, sought an American-made trombone that could produce a traditional Germanic sound and gave Conn their antique as a reference.

These Conn 66H trombones are not commonly found, so if you happen to possess one, please email me. I would love to hear from you as I do like to collect this model!
