I was aiming for the sound of a Gardella Crescent or a classic Otto Link, but it ended up sounding more like a Becherer, so I'm selling it. The tip opening is about 107. It's made of solid brass. No plating. There are minor scratches from the manufacturing process. Also listed on other sites (Yahoo Auctions, etc.). May be sold out. Please be aware that the price may vary due to fees.
