Several transverse flutes marked HOTTETERRE with the device of an anchor, discovered within the last hundred years or more, have provided actual specimens of the alleged result of the Hotteterres' efforts. Specialists in woodwind history are generally aware of three "Hotteterre" flutes—in Berlin, St. Petersburg and Graz—all of which closely resemble the one in Picart's engraving. However it has recently been shown that two of these are nineteenth-century replicas of a specimen now lost, and only the Graz example is in fact the work of Jacques Hotteterre or his father, Martin.Ardal Powell, "The Hotteterre Flute: Six Replicas in Search of a Myth", Journal of the American Musicological Society 49, no. 2 (1996): 225–263. 21 September 2012.
