Brass slide bar that provides a warm tone. - Model: Dunlop 222 Brass Slide - Size: 9 - Length: 60mm - Wall Thickness: 15mm - Inner Diameter: 19mm - Material: Brass This is a slide bar for bottleneck playing that I bought about two years ago and kept stored away. I found I had some older ones, and this is an item I've never used, so I'm offering it for sale in case anyone is interested. Thank you very much. Thank you for looking.
