BP Coach Gun Lock Mechanism - work needed

[Rack Grade]

Who out there could do the following work and/or locate the right part?

- The gun: W.G. Rawbone 20" percussion coach gun, 10 gauge

- The problem: screw head for the screw that holds one of the hammers on has broken off

- The work: (a) back out the tiny screw shaft, if possible. (b) locate or fabricate a replacement screw with a tiny bit of scrollwork. (c) install new screw

She is a small screw and and screw shaft - delicate work to be done. Gun is not a high value gun, but she's a nice historical piece and I want to fix her.

Any thoughts please let me know.

Thank you all!

These hammer screws were typically in 4/40 or 5/40 thread and not too hard to find. Backing out the broken piece is a bit more difficult and a dremel with fine diamond bit will be your best friend. Get a hole down the center then tap on a very small phillips screwdriver into that hole and reverse the piece out. Sometimes works for me.
