Musket made of parts from different guns
I have a musket that appears to composed of parts from different guns, and I am looking for information on the parts. I am pretty sure the stock is from a US Model 1816 Musket, but I am looking for information on the lock and the barrel.
The lock is a would-be Tower lock: it has the word "Tower" and the crown in the right places, but lacks the year and the monarch's initials. Inside, it appears to have the letter “D” on the mainspring.
The barrel has the initials "N J" on the side opposite the lock. On the bottom, I found the marks "6⁰ N 10" grouped together at one spot, and the single letter "S" at another spot. The barrel has a production year on top, in the breech area. It appears to be 1801, but the third digit in the year is gouged and difficult to read. A little farther forward on the top of the barrel, I found some initials, but they are very difficult to read. I think the initials consist of one or two letters followed by “& P” (or maybe “& D”).
The ramrod, which appears to be from yet another gun, has the numbers “5 5” and small crown on it.
I have been told that the "N J" on the barrel probably refers to the New Jersey militia. (The musket was found in a house in New City, NY.)
I have attached some pictures of the gun and the parts. I would appreciate any information that anyone can provide to help me identify the origin of the musket’s parts. Thanks very much.
