Delrin in D with the figured rings. I bought this one off the board in March. Financial changes drive me to sell. Already gone.
And it is a Jon c. My mistake. 
This will be a great flute for anyone in the market for a quality delrin flute.
Which model is it? (Pratten, Rudall and Carte…?)
Hugh
Maybe it is a fake, like the fake R&R flutes, as I don’t have a “h” in my name? 
I did come across a flute on eBay with “Cœchrån” stamped on the barrell. It was touted as a copy of a “Randall, Rhodes & Carter corrugated bore from the MST-3000 series.” The “Buy It Now” was for £1800.
“corrugated bore”
Oleander wood with led keys…
obviously not a real Jon.C
