here are some more pictures, this time of barrel markings. The first two are on the underside approximately 2 and 8 inches from the breech end of the barrel respectively. the third one is right at the breach on the underside, the next one is right on the back of the breech plug. theres also a small mark of a letter, maybe an E, in a circle on the left side opposite of the nipple, and a small hallmark inside the lock of an F under a crown.
