Well, it appears to be a '61 lock with a '62 date. I blew up the picture as far as I could and it looks like corrosion and wear has distorted the 6 and 2 to appear like a 57. The picture pixelates (sp?) too much to do any better. The bolster has been altered too much to even tell if it's from either a '61 or '63. Too much metal has been removed for it to even fit the plate cut-out. I couldn't tell if there are any remains of a clean-out screw. But the barrel appears to be from a '55 or '61 and when considering the following, may have been from a rifle. Now the stock I'm sure is from a '55 Rifle. Note the distance between the lower band and the forward band spring mortises. I can't read the entire tape measure, but there is at least 14 inches between the lower band (which is from a '63 Type I) and the original position of the upper band. There is about 11 inches between these two bands on the Rifle-Musket. The nosecap appears to be in the right position and original to the gun. It looks like about an inch of the barrel at the muzzle may have been cut off, but can't be sure. It would help if we get a measurement of the barrel from the tang line to the muzzle. If it was a rifle barrel, the bayonet stud is gone. But I'm leaning that way because the rifle barrel was somewhat thicker than the musket barrel and if this one fits the channel well, it's likely a rifle barrel because this is a rifle stock. 'Bout all I have for now unless we get some close-ups and different perspectives. Interesting piece, just wonder what its story is.
Just looked again at the pic of the muzzle. Doesn't seem to be much at all if any barrel missing. Need a measurement. Sight looks like a replacement though.
