Colt 1851 London Navy Variants: In addition to the features listed on page 1.6.2 the London pistols are known to have 3 and 4-screw frames together with "round" triggerguards.
Ca. 42,000 specimens were completed and/or produced in the London Colt Armory between 1853 and 1856. The so called 1st models of ca. 2,000 units were partially built in Hartford and completed in London. Most such specimens have silver plated brass backstraps and oval brass triggerguards. Collectors call them Hartford-London Navies.

Original 1st and 2nd model London Navies are recorded with beveled loading notches of a size larger than the previous "V" shaped ones in the squareback models. Thanks to these beveled loading notches round, conical balls and paper cartridges can be loaded. In the making of subject Uberti miniatures, however this aspect was disregarded and the "V" type notch of the earlier Squareback models were cut.
All Uberti miniatures of Colt 1851 London Navies in the Hunzinger Collection share period correct loading lever plungers screws entering from the left side and round triggerguards. Triggerguards and backstraps are made of steel. Two variants are noted:
The overall length of the miniature shoulder stock of 4-screw frame Colt 1851 London Navy #PM146 in the Hunzinger Collection is 20,60 cm/8.11 inch. This makes this Navy shoulder stock a mite shorter than the one fitted to the Colt 1860 Army miniature #323 presented over in chapter 220.127.116.11.
