The model 1855 rifles were manufactured at Harpers Ferry in 1857-1861. Around 8,700 were produced, of which 5,151 had iron mounts. It has standard markings and features including an "1860" dated lock, a partly obscured barrel date that appears to be the same, "V/P/eagle head" proofs on the left quarter of the breech, eagle and shield motif on the primer door, blade front sight, a sword bayonet lug, rear sight with flip-up leafs, iron fittings, left stock flat stamped with two bordered script inspection cartouches, and "US" marked buttplate tang. Includes an extra nipple and worm tool inside the patchbox.

Very good, with traces of brown finish on the once cleaned barrel, 30% applied niter blue finish on the lower trigger guard/tang assembly and buttplate, with moderate flash pitting, scattered patches of light freckling and corrosion, defined lock markings, a obscured barrel date, and defined breech proofs. Stock is fine with scattered scratches and dents, a few small chips, a crack visible behind the lock, and defined edges. Mechanically excellent.
