The Gibbs carbine is one of the scarcest and best designed carbines used by Union forces. Only 1,052 Gibbs carbines were manufactured by William F. Brooks of New York City at the Phoenix Armory and delivered to the U.S. Government in 1863 due to the factory being burned down during the New York Draft Riots in that same year. Reportedly, 500 of these were issued to the 10th Missouri Cavalry and smaller quantities were issued to the 13th and 16th New York Cavalry. An Eagle marked on the lock behind the hammer and "Wm F. BROOKS/MANFr NEW YORK/1863" marked ahead of the hammer, patent date marked on top of the breech, "144" stamped behind the lower tang, two boxed script inspection cartouches stamped on the left of the buttstock, and "U.S." marked buttplate tang.

Very good, with mostly bright gray patina, some scattered light pitting, strong traces of original blue finish in protected areas on the barrel, strong patterns of original case colors visible on the lock and breech underneath mild freckling, and clear markings and edges in the metal. The revarnished stock is also very good, with a semi-circular crack visible on the left between the sideplate and the breech, some scattered dents and scratches, and lightly visible cartouches. Mechanically excellent.
