Circa 1900, Bisley with matching numbers, 5.5″ barrel and cylinder are replaced with .45 Colt SAA presumably to change caliber. Very common practice. Barrel and cylinder are period correct. Frame, trigger guard, and base are all matching numbers. Period correct faux ivory, most likely Bakelite. Case hardening is very fine. Function is very good. Lock up is very tight. No rust. C&R Eligible. Second listing.
