I've had for many years an old rolling block of unknown origin and caliber. It has a emblem on it, a crown (maybe an Enfield?) Then, under it it has AR.O,with the A's right leg the staff for the R. Under that is 1877, probably the year of manufacture. The Rolling block has a serial number on it, but only the last 3 number are visible.
It's bore measures .435. Barrel length is 37"
It's a "Buffalo rifle" looking gun full stocked to within 4 inches or so from the muzzle and has a cleaning rod under the barrel.
I got it probably 40 years ago.....my father was going to make a lamp out of it, but I pitched a hissy fit and he gave it to me......(right after the a$$ whipping for throwing a hissy fit)......
Any idea's?
