A word of caution: Many years ago I purchased a nice looking carbine. Quickly found it shot high. Brazed an extension on the front site. Things appeared great until I noticed that it was really load sensitive. Careful looking at it revealed through the now worn parkerizing, that the receiver was a "re-weld" and the barrel had the remains of a pin welded up. My suspicion is that it was a blank firing movie prop. Immediately it was disassembled and the parts used to make up one with a new commercial barrel and a salvage receiver. Note: this gun is stamped to prevent anyone selling it as an original.
