DescriptionTechnical description: Probably violet wood with german silver keys and crook. Crook well and sockets lined with german silver. Fully automatic octave keys. There is an F resonance key (opening with the F key) on the right side of the instrument below the F key. A conservatoire action is operated by R2 and R3 but not by R1. The low C key lowers the R2 and R3 rings and closes the brille.

Usable pitch: Probably originally Diapason Normal, but with the present crook the instrument plays at A₄ = 440 Hz.
Performance characteristics: The instrument is leaking too seriously to establish any more than the most general points. It plays with a good rich tone quality. The crook is unusually short suggesting that the instrument was originally built to play at a lower pitch, the change in the position of the second octave key may also be connected with this change of pitch.
Repair History: Hole for the second octave key has been moved a distance of c 9mm up the instrument, the position of the original hole is clearly visible filled with a darker wood. The 8.2 key appears to have been cut and altered in length. |
