Remarks
Outward design and key design point possibly towards 2nd half of 18th century.
‘French’ according to the MIM file.
This instrument was part of the Fétis Collection, sold to the MIM in 1873.
A number of elements, however, make it assumable that this instrument has been adapted in the 19th century, or is a 19th century copy after an 18th century example:
- The reed well is metal lined The minimal bore is relatively narrow, staying narrow after the reed well. Consequently this reed well allows only narrow-bottomed crooks, type E. horn. The metal reed well is probably to enable the insertion of a corked crook. According to Mahillon (R1978) Vol. I p. 236 "a modern bocal and reed had been added to use it instead of a cor anglais".
- Springs attached to the keys.
- Varnish does not look 18th century.
- Tone-holes are relatively small.
