HELP ! Need a part
 

Seems that while cleaning up this old gun (1885 12ga. s/n 46650) I found an old repair to the right hammer shaft. While reassembling the receiver I cocked the hammer to reinsert the firing pin and broke the old repair to the hammer shaft.

As you can see by the pictures the right hammer is a bit different from the left side so it has been repaired before.

Does anyone have a part that would work to replace the broken shaft and maybe a hammer that would match the left side??

Your tumbler is broken. That is what the hammer attaches to. And your hammer on that side is not correct either.
If you want to contact me, i can at least help with the tumbler. Maybe the hammer too.

I make parts to work and match, harden, fit, make sure they function properly, be happy to help
