The lock and barrel of this example are dated 1854 which was the second to last year of Model 1842 production. It is also marked with the standard Springfield markings. This example is one of 14,182 Model 1842 muskets altered by the national armories in 1856-1859 by rifling the barrel and adding a long range folding ladder rear sight of the style seen on the Model 1851 cadet muskets. The latter feature was used on just under 10,000 of the converted muskets.

Very good with mostly bright surfaces, some light spotting, light to mild pitting, and vice marks. The stock has some chips at the edges and general scrapes and dings. Mechanically excellent.
