Restored by Jon C. a few years ago, I bought it on february from another forum member.
It’s an antique flute in cocuswood with six nickel silver keys (short foot) made by Henry Potter around 1860. Have a look at the maker’s biography: http://www.mcgee-flutes.com/henry_potter.htm
The holes are big and the bore is similar to a standard Rudall one. It has a very nice tone, very warm and “round”. Its very light in weight and feel when you play it and requires little air. It’s in tune at 440hz with the slide opened about 1,5 cm, more or less depending on the player. Notes A and B has been flattened by reducing the tone holes size with shellac, a very good job by Jon C..
Here you can find some pictures and some little more info:

Being the blow hole not so big, it requires a focused embouchure, but when blown properly, it can get quite loud, and it’s surely capable of being heard very nicely in a session, even if not with the same ease than a well made modern flute.
It has been my only D flute for months, I also do concerts and it has behaved well. I chose it over my old Lehart flute because I liked its tone better.
I’ve changed two pads on short F and Eb keys, but since I’m lazy I didn’t use shellac or glue to attack them, but blutack… It worked perfectly, the pads have been stable for months, and if needed can be easily removed without being dameged. The Bb key moves slightly on the side, at times it’s better to check if it’s in the right position and closing the hole properly. I do use the key successfully though. The crack on the barrell that was repaired has reopened through the glue some months ago, but being very thin it has closed again. I play the flute with black tape on the crack just to be sure it stays airtight in every situation (and it has), I didn’t glue it back because again I’m lazy…
Here are a couple of videos of me playing it, there are a few months between the first and the second one:

I’m selling it because I’ve recently got another antique flute with the foot keys that I like more. I’m looking for 800 euros + shipping, the flute is in Rome, Italy. No case, sorry.
On the 17th I’ll have to play at a wedding and I’ll need this flute (I’m not yet used to the other one), I can’t ship it before.
Of course I’m available for any question
