I'm working on a Miroku o/u for a local high school trap shooter. It's an early gun with the 2 hole firing pin bushing. The right (upper) mainspring is broken. Do any of you have one in your junk drawer. If not I can make one. just trying to get it up and running as quick and cheap as I can. Thanks much Mark
They don't have any and Wisner's discontinued them. Correction the right hammer is for the bottom barrel . When I got the springs out the left one was about 1/3 thicker through the limbs. I have no idea who else has been in there and if the springs were in the correct sides. Any insight is greatly appreciated. Mark
It is a simple spring to make as far as I remember it was 1/8 thick 3/16 wide but it has been years since I have repaired one.
Wow, what a wonderful website related to the question.
