Over the years I have gathered a set of 24 small brass trumpet bells (2 inches high by 2 inches in diameter at the base). I intend to attach them to a leather strap but first need to replace some of the clappers. Some have no clapper and a few have an old nut on a wire as a clapper. Does anyone know of a source of very small clappers; preferably brass. The knob of the clapper should be about 1/4 inches in diameter.
