This is an extremely rare example of possibly the only known silver finish Sheriff's Model Colt Single Action Army revolver with a 7 1/2 inch barrel. The accompanying factory letter verifies the caliber, barrel length, silver finish, grips as "Not Listed" and that it was shipped as 1 to Simmons Hardware Co. C/O W.E. Todd in St. Louis, MO, on February 15, 1905. The top of the barrel is marked with the one-line Hartford address, the left side is marked "45 COLT", and the left side of the frame is marked with the two-line, three patent dates followed by a very faint remnant of a circled Rampant Colt. The matching serial number is marked on the bottom of the frame, trigger guard and back strap (weak). Standard blade front and frame notch rear sights, and fitted with smooth pearl grips.
