Based upon the French Model 1849 Chasseurs de Vincennes rifles for the French light infantry, these large bore, sturdy rifles were produced on contract for the US Navy by Whitney circa 1861-1864 with 10,000 produced. Roughly half saw Civil War service, with the remainder staying in storage at various US Navy yards. In an interesting footnote, at least a handful of these guns were acquired by the OSS during World War II for use by indigenous guerrilla fighters in the Pacific and CBI theaters of operation. This is probably the only example of a Civil War era firearm seeing service during World War II. {ANTIQUE}
