Notes on this instrument

The New Langwill Index reads:

“…by 1911 the firm was making every kind of musical instrument, employing a workforce of 1000 at eight factories, the then largest single musical instrument manufacturer in the world… 1925 claimed to have made over two million musical instruments at their six factories; however by their 1927, when the firm celebrated its centenary, the workforce had dwindled to 200… Among their ‘predecesseurs et maisons réunies’ were the wind instrument-making firms of Association Générale des Ouvriers, Feuillet, Gautrot aîné, Guichard, Lecomte, I. Lot, Massin &  Thibouville, Triébert, Tulou and others.

In that sense, Couesnon can be seen as the link between 19th century instruments, and the 20th century.
