A friend of mine recently came into possesion of the percussion firearm pictured here. He brought it to me to take a look at it, but I have very limited experience with originals and was hoping someone on this board could help identify it and / or shed some light on its origin.
The bore is .63, rifled with 16 narrow land and grooves. The barrel is 34.75 inches long and is swamped. The breech is 1.240" across the flats, the waist is 1.000" and the muzzle is 1.115". The length of pull is 12 inches (to the front trigger)
The firearm has only two marks of any kind on it that I can find. The lock is stamped with the letters "R:LM"
The barrel is marked on the underside of the breech with what looks to be a "BN".
Some additiona photos of the gun.
The barrel has a hooked breech and is retained by three very well made keys.
The gun has a beautifully made, very compact set trigger mechanism.
It also has some odd features. First there are two bosses on the right side of the muzzle. One is dovtailed into the barrel side flat and has a male threaded stud. The other looks to be forged as part of the barrel and has a female threaded hole in it.
The rear sight is made of brass but has two steel leaves. The lower of the two has a notch and a peep hole. The talled leaf just has a notch.
The butt stock has been poorly fitted with lead counter weights. The holes for the weights were drilled off center and it appears the lead was cast in place as the stock cracks that communicate with the lead cavities are filled with lead. It looks as though the heat of casting cracked the wood and the cracks filled in with lead while it was still molten.
The butt plate has an odd protruding heal screw
The front sight is very low, very close to the muzzle, and is made of brass.
The lock appears to be very well made and still functions prefectly (as do the set triggers).
The barrel has also been 'demiled'. You can see in the next photo a bright metallic dot on the barrel left side just aft of the muzzle. It is not rusted like the rest of the iron work and is a pin protruding a short distance (~0.100") into the bore and filed flush with the barrel flat (although it looks like stainless steel to me, it is flush with the barrel, which is rusted uniformly, and there are no file marks on the barrel around the pin). There are three of these pins along the length of the barrel, all on the left side. They do not alter the outside appearance much but render the bore un- shootable. I have no idea why anyone would do this except to make it unservicable. The photo of the bore shows one of the pins protruding into the bore ID.
Any help identifying this firearm would be greatly appreciated.
Thanks
