Colt 1873 SAA – "New Model" or "Smokeless Frame": The cylinder pin of these models is kept in place with a transverse cylinder latch, the ejector rod is equipped with a "half-moon" shaped tip.
The half-moon or crescent shaped ejector rod buttons were introduced as early as 1882 in original Colt SAAs but the cylinder base pin held in place by spring-loaded cross-pin screws was launched in 1896 only.
The latter date commonly defines the switch from the so called black powder to the smokeless framed Colt Single Action Armies.
Nicely replicated key features of two Uberti miniature Colt SAAs: "New Model" #2553 (lower pistol) features transverse cylinder latch and crescent tip of ejector rod but "Old Model" #3400 (upper pistol) has cylinder pin secured by screw through front of frame and bullseye ejector rod head
A not too serious caveat is in order here: Many aficionados of the venerable Colt SAA enjoy Cowboys and Indians movies, too. If the story of this western you are watching takes place during the 1870s or 1880s but the hero or the bad guy is toting a smokeless framed SAA - which is what most of them do - then the prop master of the movie did not issue period correct irons. In other words you were watching another one of these Hollyweid flicks.
No offence intended but in his many Western movies the cowboy characters of John Wayne usually carried a smokeless frame SAA with the half-moon tip of the ejector rod.
