Technical description: Boxwood with german silver keys and four ivory ferrules at the sockets, reed well and bell. Sockets and reed well are unlined. There is an onion shaped baluster at the top of the instrument. All the keys are levers with the exception of the B?-alt. The octave key is hinged at the back of the instrument within the onion, the vent is at the front of the instrument and the pad is mounted at the end of a semicircular curved arm. The key is kept closed by a flat spring under the touchpiece. The G? key and vent are both on the middle section. The R0 support is a wooden block. The linkage of the low B key between the middle section and the bell is by a small tenon which is inserted into a socket in the bell part of the mechanism.
