Bird flageolet

"Rosewood, in three joints comprising cap, head and main joint. Seven fingerholes and no thumbhole. The highest hole is bushed [narrowed] with ebony to leave a narrow aperture next to the upper rim. The next three holes contain annular bushes, leaving a very small central orifice in each case. The lowest hole is offset to the right side. An ivory mouthpiece is inserted into the cap".
