Also known as the "Union Carbine", this Type II example was manufactured by Edward Gwyn and Abner Campbell of Hamilton, Ohio circa 1863-1864. The carbine has the Type II pivot-type lever latch, flat hammer with beveled edges, short lever, and short base rear sight. A sling bar and ring are mounted on the left side of the receiver. The lock plate is marked "GWYN & CAMPBELL" in an arch above "PATENT/1862/HAMILTON.O.". And "UNION/RIFLE" is stamped vertically on the right side of the receiver. The matching serial number is stamped on the bottom of the receiver, underside of the barrel, loading lever, breechblock lever latch. Single letter Ordnance inspection marks are stamped on most components. Pinched blade front sight and folding ladder rear sight graduated to 600 yards. The barrel is blue, the breechblock and upper tang are a niter blue, with casehardened remaining parts. Mounted with a smooth straight grip walnut stock with a sharp boxed "WHR" cartouche on the left wrist and a small "WHR" sub-inspection mark on the stock comb just ahead of the buttplate tang. Gwyn & Campbell manufactured approximately 4,000 Type II breech loading carbines in 1863 and 1864. These carbines were issued primarily to Federal cavalry regiments in the Army of the Cumberland and the Army of the Tennessee.

Excellent. The carbine appears to be as issued and unfired showing only very limited storage wear. The barrel retains nearly 98% of the military blue finish. The rear sight, breechblock, upper tang retain 95% of the fiery niter blue finish. The remaining surfaces retain nearly 98% of the vivid case colors. The stock is also excellent with minimal handling/storage marks and a sharp cartouche. It would be very difficult to improve upon the condition of this excellent and original Gwyn & Campbell Type II Carbine.
