This excellent Harpers' Ferry M1855 lock is among the rarest locks on the market today. These 1861-dated locks were in production at Harper's Ferry when the Confederates captured the arsenal in April of 1861. This lock is all correct according to John Willyard's excellet book, U.S. Model 1855 Series of Small Arms. It features original color case hardening, indicating that this lock was likely built for an iron mounted rifle, as musket locks were polished bright. It is in excellent condition and is fully functional; although the tape primer system has been removed. This is the rarest and most sought after lock we've ever had; it is very unlikely that we'll ever have another '61 dated Harper's Ferry lock; let alone one in this condition. Don't let it get away!
