Antique Flageolet 6 Key Flute w mouthpiece Gottlob Huller Key D Low Pitch

Description

Being offered is a Flageolet Flute. I KNOW NOTHING ABOUT THESE!!!! It took me several hours to figure what it actually was. The estate sold it as an Oboe but I knew it wasn't that or a regular standard flute. There are some markings on it that are very worn and I cant make a lot of it out. I do see a music symbol and some markings on both side and under it, On the left it looks like it starts with an FR..then numerous letters that I cannot even come close to guessing then possible ends with a K? On the right of the Music harp looking logo is a few flags and inside the one it looks like it says Mark 1. Below the symbol is the letter D and below that is L and I think P. Total length is about 16 1/4 including the screw in mouthpiece. The MP looks worn and has a very tight crack on both sides. I count 6 keys that all seem to spring fairly strong. I would guess the pads are shot. Again, I do not claim to know this so your opinion on the spring action could be different. This has 3 pieces No idea if the mouthpiece section is replaced since it is a different stain and possible wood? IT fits very well over the cork connector. The second connector to the last is connected by what appears to be a brass connector and again fits very well. I do not see any cracks on the outside ****************UPDATE FROM A FELLOW ENAYER******************
That logo with the lyre in it belongs to the Bohemian woodwind maker Gottlob Hüller from the town Schöneck (GHS)
The letters D L P below mean: In the key of D, and low pitch (L.P.) This maker, Gottlob Herman Hüller established his workshop in 1884 in the German town Schöneck, located in the Vogtland region of Saxony. I would estimate this instrument to have been manufactured in 1884 at the earliest, and no later that the outbreak of WW2 - which is 1939.
