FL ?> Faults
Good condition. Ivory mount on MJ cracked. Leather on MJ worn out in some places. Some scratches on body. All pads and springs seem original.

PA ?> Playing Accessories
None. Mahillon (R1978) Vol.II p.253 mentions a bocal and a reed. These are not with the instrument any more.
-
UP ?> Usable Pitch
Best result was obtained with a reed TL 49mm / staple 27mm / tip width 9.5mm and a bocal TL 93mm ø 6mm + 3.1mm giving as a result A = c.438Hz.
-
PC ?> Performance Characteristics
Nice and warm sounding instrument. Quite a lot of resistance.

Remarks
Triebert mentions on p.7 of his catalogue (1855) 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].”
Some elements point into the direction of an instrument c.1830 with a few later changes or additions:
- The instrument shows many similarities to the 6-keyed curved English horn depicted in Brod’s oboe method (1830) p.107 (Planche V), including the typical bridge-like design for C-C# keys. On p.108 Brod claims the invention of the ‘see-saw’ key (“la petite bascule”).
- The G# and C#-trill keys are most probably later additions, given the other key style. The octave key looks original though.
- The reed well, being metal lined but conic, could be a transition technique for the later cylindrical reed well. It is not clear whether the metal lining of the tenons and sockets is original.
The specific mark on this instrument – if not a counterfeit – seems to contradict the long-held view that the barbican tower with 4 merlons is identifiable with Triebert instruments from after 1881.
