Hammer for sidelock percussion

Looking to find a hammer and screw for a Thompson center New Englander picked up a 54cal that hammer is missing

Darn, I'm almost positive I have a hammer and screw but I'm in FL and won't be back home until late May. I don't know for certain but if you can hold off until then I'll send it to you. I believe its from a Lyman GP but it should fit just fine.

If you can't wait I see a bunch of hammers on Ebay for a reasonable price.  I'm sure you can find a screw and washer in a hardware store to match the threads.  You can blacken a "silver" screw by heating it up cherry red and dropping it in oil.
I believe this one is from a T/C Hawken/Renegade (all the T/C locks are the same except the Cherokee and Seneca):
