This small delicate flute in Bb is marked Kelhermann facteur in Paris. It is a quality and well made flute. Not much is known about this maker except that he worked in Paris and partnered with Bonnel (originally from Rennes). I have the original box for this flute, but it's in rather poor condition, though it bears Bonnel's mark. Weight is 240 g, the sounding lenght is 540 mm. The flute is playing on its old pads, do not pretend too much, but the flute is in playing condition.
