Dave williams 4 key blackwood

hello there
Am new to the forum but have a williams 4 key flute I would like to sell as I have finally admitted I don’t use the keys.
have no idea of the value of it other then it is very good quality, and have no idea how to go about selling it.
any help gratefully appreciated
cheers

I have one. It’s a fine flute based on an 1840’s Rudall but with a short foot.

A 5-key was offered on eBay in September for a start bid of $1900, with a Buy It Now price of $2100. No bids.

A 4-key was offered here on Chiff & Fipple for $1350 including an extra headjoint, in March 2010.
