I was given an H&R hammerless, top break .38 S&W revolver. It is in fairly good condition aside from being apart & missing a few pieces. It is marked on the top of the barrel: Harrington & Richardson Arms Co (with the o in Co underlined) Worcester.Mass.U.S.A. .38 S&W CTGE is on the side of the barrel. I've been using the parts list from Numrich arms to identify and replace the missing parts. I've gotten a replacement trigger spring and a replacement hand with spring. However, the Numrich arms page shows a small coil spring to move what they call the sear. In my revolver, there is no place for coil spring. Also I can find no listing for a spring that will hold the lifter against the hammer. Can anyone help?
