My wife bought me a nice looking German flageolet. I have heard these instruments described as csakan but I was under the impression a csakan is a little different: http://www.csakan.de/en/
In any case it’s essentially a keyed whistle.
Unfortunately the blade looks damaged but I plan on trying a laminate insert.
The bottom octave is nice an full but it won’t play above second d.
If you push the block of that Csakan in a tad you may find the higher notes easier to play. More air will go up and over the edge rather than down and in. Try it bit by bit.
I have a Von Heune alto recorder whose edge developed a chip. Friederich Von Huene himself repaired it for me to almost perfect condition. He somehow built the edge back up. I’ll take a closer look and see if I can give you any suggestions.
OK-- it looks like he glued some very thin plastic* to the inside bottom of the blade, then filled the top surface with a wood tinted filler. This might be either epoxy with matching wood dust for color, or possibly cyanoacrylate glue dripped onto a small pile of that dust. Careful filing and sanding would be necessary to get it to it’s final shape. Perhaps you can find a recorder maker in the UK who’d be willing to try. I have a photo I can send you if you’ll email me with your email address. I’m brewerpaul@aol.com
*we’re talking about plastic as thick as photo film (remember that stuff?). Exactly how he got it glued up in there is anyone’s guess.
I’ve had a Carbony on my wishlist for years. My wife finally broke down and got it for me this xmas. Fun little whistle to play. Much easier blowing than I was anticipating.
I treated myself to a Christmas/birthday present, a 2-keyed delrin Baubet flute. In fact, this very one. Francois was so kind as to make a demo clip after he finished it.
Looking forward to receiving it!
Santa was good this year. I received a Killarney from my folks (really enjoying it!), and then I was the winning bidder on eBay for an MK Kelpie (should be arriving this week).
I had one exactly like that, which I bought directly from Ralph around 1978-1980. Rosewood. It was a fine instrument, just too loud for me, with too stiff a 2nd octave.
