I moved your thread to the Black Powder and Musket forum. You'll likely get some answers there. We have some extremely knowledgeable people here. However, I can tell you that you really need to post some pictures with any markings clearly shown as well as a good photo or two of the entire piece.
Welcome to the FTF community. Please introduce yourself to the folks in the Introduction forum.
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
