Regarding the original question... the checkering, the two-key fore end, the rear sight and the general lines of the rifle are all consistent with New England rifles I own or have owned. The socket for the peep sight isn't, although that could have been added later. The patch box and trigger guard are not the conventional NE style but I doubt that is really significant... when you see them they do indicate NE but the opposite isn't necessarily true... Still, I suspect its a NY rifle of about 1830... late for a f/l but extremely well made. It may even have been English made for a NY dealer.
