1873 Pieta 45Colt and my 1866 Henry Repro.
Howdy Again
Probably a typo. The 1866 was the first model Winchester produced under the Winchester name. The Henry was patented in 1860 and produced from 1862 until 1866 by the New Haven Arms Company. In 1866, after a dispute with B. Tyler Henry, Oliver Winchester changed the name of the New Haven Arms Company to the Winchester Repeating Arms Company. Easy to tell the difference. Although both had brass frames (actually gunmetal, a type of bronze) the Henry rifle had no fore stock and was loaded through the front of the magazine. The 1866 Winchester had a fore stock and was loaded through the King's patent loading gate on the side of the frame.
P.S. Be sure you use a soft, gooey, Black Powder compatible bullet lube on your bullets for your BP ammo. BP does not like modern hard bullet lube and you will find your accuracy plummeting after a few rounds build up a hard caked, difficult to remove, deposit of fouling in the bore.
