Originally manufactured in 1901 and subsequently professionally converted to .22 R.F. The barrel is marked with the standard two-line Colt address on top and the "(BISLEY MODEL)" and "22 R.F." caliber markings on the left, and otherwise standard markings. The cylinder has been professionally lined and a plate added at the rear to accommodate the new cartridge. The front sight blade has been ground lower and it is fitted with a pair of slightly ill-fitting smooth grips with a blank escutcheon on the left panel. Includes a leatherette wrapped hard case.

Very fine as professionally converted and refinished, retains 99% of the blue and 95% plus of the case colors with some scattered light handling marks. The slightly ill-fitting grips are very fine with minimal handling marks and some typical hairline age cracks in the butts. Mechanically fine with three clicks. The case is very fine with minimal handling/storage evidence.
