Repair History: May have started as a 12 key clarinet; the A, A♭, B♭ and G♯ keys have been modified or repaired at one stage, and at a still later date the second C keys and alternative touchpieces B♭ and spectacle have been added. The F, spectacle and G♯ key-holes have cut seating, so these are probably not original. The B tone-hole has been very neatly plugged, but the hole is clear on the inside. Wooden thumbrest probably added.
