This is a J.C.R. cowbell (half-moon). It has been used for many years, so it is rusty, but there are no dents or cracks. I mainly used it by hitting the top when I wanted a cowbell with a small volume in a small venue, rather than playing with a heavy edge strike. Recently, I haven't had many opportunities to use it, so I decided to list it, hoping someone else can make good use of it. Recommended for those who seek tightness over volume. The back is wavy, but it has been in this condition since I bought it new. The black cover in the photo will also be useful for shipping, so I will include it. I apologize, but please refrain from price negotiations.
