Manufactured from 1870 to 1890 after Colt purchased the rights from the National Arms Company. The top of the barrel has the standard two-line Hartford address followed by "No.1" in between a pair of Maltese crosses. The frame has the standard engraving and checkered panels on the grip area. The letter "G" or "O" is stamped ahead of the trigger, and the barrel and grip have the serial number on the bottom.

Good. The pistol has a mottled gray patina with light pitting and oxidation and several dings. The action function fine. The barrel marking is faint.
