I have a musket, the lock has "POTTS&HUNT" with "LONDON under it. There are two small marks just above the front lock screw but I can not make out what they are. The barrel has the correct proof makes and is 33" long. The stock has the number "217" stamped in the wood on the right rear of the stock next to the butt plate, and a crown with the letter"H" just to the rear of the trigger guard. The rear sight is missing but you can see where it use to be, what is strange is it appears to have been located 7 5/8" from the breech, odd I thought. The other odd thing is that the bayanot lug is on the front band and it has the number "217" stamped on just like the stock. Some pictures that I could find on the E-net showed the barrel extending beyond the nose cap buy a few inchs, this rifle, the barrel only extends 1 1/2". I would like to know what I have and any help would appreciated.
