Colt 1851 Navy Variants – Squareback or "Early" Models: In addition to the 7,5" octagon barrels, 3-screw frame, brass triggerguards and backstraps, hinged loading levers with catch, cylinders roll-engraved with Ormsby naval engagement scene.
The distinguishing features of these early ca. 4,200 production models:
Trio of Colt 1851 Navies with squareback triggerguard (from top): 2nd generation Colt re-issue "father" #17297 (1975 production; courtesy Dieter Hummel Collection), note loading lever plunger screw entering from the right side; #530 "son" with charcoal blued barrel & cylinder, loading lever plunger screw entering from the right side; #PM3 "son" in "Cowboy-Quality" enhanced by one-piece ivory grips, loading lever plunger screw entering from the left side
Renowed Colt 1851 Navy researcher Nathan L. Swayze describes two (2) Navy models with squareback triggerguard, naming them the 1st and the 2nd model. Their differences are narrow only.1) Bearing this in mind Uberti disregarded these subtle differences in the making of their miniatures of the "early" 1851 Navies.
A number of Uberti squareback miniatures of Colt 1851 Navies of the Hunzinger Collection including those sold through the United States Historical Society (USHS) are noted with loading lever plunger screws entering from the right side, see #530 in the center of the above picture or below in the comparative pictures and among the cased variants.
A few other "early" model Navies in the Collection obtained through channels other than the USHS program have that screw entering from the left, like you see in #PM3 at the bottom of the above picture and #783 further down on this page, too.
Both ways of screws entering the plungers are historically correct.
All squareback miniatures in the Hunzinger Collection share the "V" or non-beveled "small" type of loading notch found on the right side of the barrel lug.
