Black plastic endpin cover for Oscar Schmidt's current 1930's reissue models (OS73C 21-bar and OS73B 15-bar). Cover flips open to change strings. This pin type of string attachment makes an autoharp an A-model harp. NOTE: Also works on older Oscar Schmidt autoharps with pin-type string attachment on the bottom end of the harp. Cover is somewhat smaller than the end of the older harps, but covers the pins well and looks nice.
