A customer of mine brough in a little H&R model 732 .32 cal revolver that had no tension on the hammer. Upon disassembly I seen that the plastic "guide" that sits on top of the mainspring rod was broken. I've checked various online sources, and they are all sold out of this. Apparently, H&R switched to a different style mainspring assembly that fit into a little detent on the bottom of the hammer. I don't care which version it is, plastic or new style, if anyone has one of these lying around, I could sure use it! Thanks!
