If you go to the last flute on the page, you’ll see a G. Cloos NY circa 1890 Third Flute. Here is their description:
Shown above and below is a small "third-flute" by Cloos, so called because it has six-finger note f', a (minor) third above d'. It is unusual in having a full eleven keys and a "B-foot" (sounding d'). Most third-flutes are simple instruments with one, four, or six keys and with low note f', i.e. without an extended foot. The flute has a charming sound, with a bit of piccolo-color.
Although my flute is all black, it is exactly what you see in the picture (see my attached photos). Mine is stamped GEO Cloos and has what I believe is a serial # 702. The 70 are very clear and there's only one more digit that could be a 2 or a 3. It is stamped in two different sections. I read elsewhere that a serial # of 2270 would be 1900. So I'm thinking 1890 or earlier is a good estimate. Mine has a crack that the store believes can be repaired. They also believe that the flute can be restored to playing status, without too much effort. I am researching this flute in order value it for my father’s estate and any guidance or input you have would be greatly appreciated. Before we can donate/sell/or purchase items from the estate they mist be valued
Thanks for any assistance you can provide
