In 1867 Whitney sold 6,943 US Springfield Model 1863 Rifle Muskets that he had acquired as surplus after the war. These guns were stamped with the Whitney Arms Co logo on the stock and typically had their barrels and furniture blued. Likely many of these guns ended up seeing service during the Franco-Prussian War. A very nice example of a completely correct US Model 1863 Rifle Musket that was then resold after the war by Eli Whitney Jr.
