The authority among the Colt 1851 Navy researchers is Nathan L. Swayze. He describes two (2) Navy models with round triggerguard, the 3rd with small rounded triggerguards, and the 4th model with large rounded triggerguards.1)
The "late" Uberti miniature Colt 1851 Navies recorded are fitted with "one fits all" rounded triggerguard. In other words in the Uberti miniature Colt 1851 Navy line this narrow difference is disregarded.
Later variants of the 3rd models and all of the 4th models feature beveled loading notches of a size larger than the previous "V" shaped ones used in the Squareback models. Thanks to these beveled loading notches round, conical balls and paper cartridges can be loaded easily in the originals and in the Uberti replicas as well.
In the making of Uberti miniatures this property was ignored and barrels cut with the "V" type notch of the earlier squareback models were installed.
All "late" Uberti miniatures of Colt 1851 Navies of the Hunzinger Collection have the period correct loading lever plungers screws entering from the left side.
