This is an Overton tin whistle. I acquired it on eBay around 2007. There are scuffs and scratches on the mouthpiece and body. Please refer to the photos for details. It's a non-tunable (one-piece) soprano DC whistle. I got it used, so I don't know its origins, but it seems DC whistles were made to order. It has seven finger holes on the front. When all the holes are covered, it plays C, and the thumb hole on the right side switches between F and F natural. That's what the tuner showed. The manufacturing year is 2005. The mouthpiece marking appears to be 0.5mm, but I'm not certain, so please judge from the photos. When I play it, I feel a lot of breath resistance. Unfortunately, this seller, who can't even control a whistle with six holes, couldn't handle the DC whistle and it has been sitting unused since I got it. If you think you can handle it, please do. ---- Regarding the price, it's set quite a bit higher than originally intended. I will actively consider price reduction requests. I will also consider price reductions that exceed the range allowed by the request function, so please feel free to suggest a price in the comments. (Please note that I may not be able to meet your request.)
