Besson Enharmonic Euphonium

This is an Enharmonic Euphonium.

As per the Enharmonic Trumpet and Baritone in the collection, this instruments featured two sets of tuning slides on the first, second and third valves, one of which is slightly longer than the other. When the fourth valve is pressed, air is redirected through a different path in the valves, such that the longer slides are used if the first, second or third valve is pressed.

Unfortunately, this instrument is incomplete, and is missing a number of slides and valves. A donor instrument is required, or significant cost and time to create the missing parts. The instrument itself is in remarkable condition, so it is likely these parts have been missing for some time and the instrument has been in long term storage.

Serial number is 111xxx.

Record indicate this instrument was manufactured in 1920.
