DescriptionBrass, German silver, single loop, tuning slide between second and third valve, removable shanks and crooks, three disc valves (1, ½, 1½), fixed disc in relief, no cork buffers, round shaft, compression spring in long guide box.
Original: crook for F
Not original: two brass tuning bits with ears; two crooks of French origin, stamped “SII” [B-flat] and “LA · B” [A-flat]; and, silver plated brass mouthpiece, stamped “EMBOUCHURE RAYEE / GUILBAUT / BSGDG / COUESNON & C[I]E / 94 RUE D’ ANGOUÊME / PARIS / No. 1”
This cornopean represents the final stage of disc-valve development. The guide boxes or tubes for the push rods—which had been used at least since the 1851 exhibition—may have provided the inspiration for replacing the clock-spring return with a coiled compression spring inside these guide tubes.
