Hey Al, you may be right on that call. It looks as if there may be a nose cap on the stock, and if so, with no bands, and a pinned barrel, it is indeed a NE Militia gun. that means that the lock is probably original to the gun as most of these pieces were made by private contracts. I don't recall seeing one with such an abbreviated comb, but that is overridden by the rest of the facts. The Springfield 1795, and its daughters, had the standard top barrel band, and on closer inspection, it appears as though this never had one, hence the nose cap. Good eye.
