This is a Pocket model without loading lever. It resembles the `1848 Baby Dragoon but has the round trigger guard of the pocket model as well as rectangular rather than round cylinder locking notches. These were loss leader guns with many having barrels shorter than the pictured 4". they were not particularly popular among colt customers as most wanted the model with a loading lever. replica makers call this one a " Wells Fargo."
