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].”
