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 don't know the exact origin as I bought it used, but DC whistles were made to order. It has seven finger holes on the front, and it seems that pressing all the way down produces a C, and the thumb hole on the right side switches to F natural. 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 considerable amount of breath resistance. Unfortunately, the seller, who couldn't even control the whistle with six holes, couldn't handle the DC whistle and it has been left unused since I acquired it. So, if you think you can handle it, please do. ---- Regarding the price, it is set considerably higher than originally intended. Initially, I planned to use the auction feature and start at a lower price, but another flute I listed previously had a problem with Mercari's system, preventing bidding just before the deadline. The bidding period ended without any bids, and it was sold at almost the starting price. Therefore, I decided not to use the auction feature for this listing. Instead, I will actively consider price reduction requests. I am open to considering price reductions beyond the requested range if you make a suggestion in the comments, etc. (Please note that we may not be able to meet your requests or suggestions.)
