Here is an extremely rare flageolet made by John Parker (active 1770–1815)—listed by Langwill as early as 1794 as a maker of oboes, basses, and bassoons, and mentioned again in the *British Encyclopedia* in 1809, which notes the good intonation of his bassoons; his recorders and flageolets are found in collections across America and Europe. The instrument is in excellent condition. Details on euterpe-flutes.com
