Colt M1862 Police revolver - 150 years ago, the Colt factory had a bad day.  It burned down. Believed started by Confederate agents, the Colt fire in 1864 put a real crimp in the company’s percussion revolver production for the remainder of the year. But one gun that didn’t burn up in Hartford, CT was this engraved Colt .36 caliber revolver.  This five-shot handgun probably sold for an elevated price in the high demand market of 1864.
