Hello,
There is a keyless Blackwood D flute by Martin Doyle on Ebay at the moment.
The instrument is his two piece Celtic design.
(I have no connection with the seller)

Above is a link for anyone interested.
Regards.
No relation to the seller … but any relation to the maker, 2TOOTS? 
I would love to think so.
2Toots, many thanks for posting this. I was lucky enough to have the winning bid for this flute. I wanted a back up for my keyed Murray but this flute is fantastic, with not a word of exaggeration. I can’t put it down.
The Doyal flutes play so well, and easily, they should be illegal! 
Assault flutes??
I was thinking sawed off shotgun. Mine is a cannon.
I am glad bogman has managed to get the flute he was after.
It sounds like he really enjoys playing it.
Glad to be of service.
