Lovely looking flute available here. I have no connection with the sale, just saw it and wished I had a winning lottery ticket.
Best wishes.

Could use some additional photos so we can get a good look at the keywork. Jon really wanted to reinforce his tenons and sockets on this one.
Have asked the vendor to put up more close ups, says he will try do it tonight. Certainly worth a closer look 
True to his word, the vendor has put up the promised close ups. Nice.
