19 flat-cup keys of German silver mounted on pillars with foot plates of German silver. Pins, rather than screws, attach axles to pillars and keys are mounted on axles with set screws to permit various adjustments. The keywork is delicate with certain duplication of French characteristics (e.g., duplicate low Eb keys on the long joint for L-thumb and L-4). A long duplicate G# key on the butt for R-thumb duplicates the usual key for R-4 which is a standard German feature. A large loop on the butt foot plate similar to that used on the octavin for the removal of the cork. Thin delicate rollers on the R-4 keys, and a large ring around the Lthumb C key to hold down D when fingering Bb and B. There is an inoperable ratchet tuning device on the wing with only the toothed section and the metal telescoping bore parts remaining. There is no crook key; the wing throat keys are missing and the tone holes plugged. Material: “Tiger” maple. Plastic (substitute ivory) bell ring. German silver ferrules. German silver German-type crook. Tube length: 220 cm. Bore: Conical. Top wing, 1.2 cm.; bottom of wing, 1.35 cm.; bottom of long join, 2.5 cm.; top long joint, 3.4 cm. Condition: fair. The bocal is missing.
There are oval cutouts on the long joint and butt which previously held inserted plates which may have indicated the maker or owner.
19-key bassoon models were somewhat common in Germany during this period. A system developed by French bassonist Eugène Jancourt, intended as an improvement to the “Buffet” system, is also noted to have used 19 keys, as well as certain models developed by Triébert.
