Welcome here. It sounds like you have a wonderful piece of history on your hands. Post some photos and all the data if you can.
This revolver forum may also be a good resource as well:
“If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.” ― Samuel Adams
