Good point on the serial number I was thinking of my trapdoor and not the muskets. So clearly you can see I have had limited time with these. :) There is no doubt in my mind this is original. There is of course patina and wear on the weapon that I don't think anyone could fake or simulate to this degree. From the muzzle end there is wear on the rifling to the degree you can hardly see it. Improper cleaning and loading techniques?, firing rapidly in haste?, or just honest use?. Aside from the very end of the barrel where there is some visible pitting, stated wear, and coloration change the rest of the weapon particularly the stock is in incredible shape for being that old. I want to get a second look at the gun but I have to work today so I will call the shop and have them put it aside for me with a small refundable deposit as I am off on Tuesday from work which is also coincidentally my birthday!
