Remarks
There are some differences from the MIM 0974:
- Characteristic gold painted festoon decoration on TJ and MJ extremities.
- Sockets are not reinforced with metal, and cork covered as on 974.
- The brass keywork differs slightly from 974.
- Very unusual octave key design for R1! Later addition or custom-made order?
Triebert (1855) mentions on p. 7 of his catalogue that “...the firm restricted the production of curved English horns...since there is no advantage any more in making them like this, given the latest improvements [on the straight English horn].”
