On most Colt hand ejector models made after 1908 (and a few before) the serial number is stamped on the frame under the back end of the barrel, and behind the crane. Swing out the cylinder to see it. Otherwise it is usually found on the butt, or on the frame just ahead of the trigger guard.

Apr 17, 2008 colt agent serial number look up, colt agent serial number lookup, colt agent serial numbers, colt agent special.38 serial 45107, colt new agent serial number gt11669, dating a colt agent by serial number, where is the serial number on a colt.38 agent. Sep 09, 2012 Back in 1950 Colt began building guns using the new aluminum alloys. The first two revolvers were the Cobra and the Agent. Colt's small frame revolvers used Colt's 'D' frame. Other guns using the 'D' frame were the all steel Detective Special, Diamondback, and several other models. I recently aquired a new (to me) Colt Agent. Seems to be in very good condition. But there was no info with it. The serial number is D-176XX - who knows the mfg date? Colt Single Action Revolvers top. 1851 Navy 1851 Navy London. Cobra, Aircrewman, Courier & Agent Commando Detective Special Diamondback MK III, Lawman.
