I'm tired of looking at this thing on my workbench. It's a modular tom mount for a 1" diameter L arm or downtube. The wing nut is not original but it works and sorry, I don't have screws for it, but you can buy them at any hardware store. Free for the price of shipping, unless you want to swap for a high hat clutch of any description. I need a reliable clutch to use as a backup. Thanks.
