Just above the terminating decorative turned bead, there is a brass pin inserted laterally, purpose unknown, possibly for a supporting bracket.
Instrument type: Flageolet
Medium: Boxwood, brass keys, flanges.; 24.8 cm.
Key Holes System: Possibly 0/6 holes originally. This appears to be a 19th century six-holed flageolet or possibly a 19th century flageolet head joint for which another body joint was constructed to receive an unusual key design to cover 7 toneholes for one-hand, likely right. Two perforated holes. Flat brass hole-covering levers, 2 of which are perforated. All are attached with flat brass flanges screwed to the body, and each terminating in hinge-like structures utilizing coil springs similar to those used in luggage hardware.
Mark Maximum: No mark.
Condition: Body section has 2 full length cracks which at first glance appear to have been repaired with threaded nickel silver cross pins, however, they do not address said cracks. Instead, they are for pre-cross pinning across that area of the tube containing 6 of the 7 toneholes which are of unusually wide diameter for such a small instrument, and include an extended flat section cut into the wood as a continuous key seat for all the pads. Consequently, the wood mass is thin and fragile.
Provenance: André Rossignol, Paris, 28 July 1926.
