Made In Harper's Ferry

Engraved on the left is "1861;" on the right is U.S. and Harpers Ferry:

From the 45th Infantry Division Museum [Oklahoma City, OK]

Charles Cameron, a War of 1812 veteran, was most likely an armorer at Harpers Ferry, though he was retired before 1861.  [Noted because of my interest in the Cameron surname]

On October 16, 1859, John Brown led a raid on Harpers Ferry.
