Manufactured in 1866. The rifle has a German silver front sight blade and a folding leaf rear sight with a 1,000 yard center notch. The barrel has the two-line Henry's patent/New Haven address legend ahead of the rear sight. An "H" New Haven Arms inspection mark is stamped on the lower receiver tang behind the loading lever latch. The bolt is fitted with a replacement rimfire firing pin, the end of the extractor is broken, and the barrel sleeve is slightly loose. The matching serial number, "12157", is on the top barrel flat, left side of the lower tang, and in the stock inlet. The buttplate is numbered "12492". The refinished stock is fitted with a late style brass buttplate with sharply pointed heel. The left side of the stock is fitted with an added rear sling swivel. Only around 14,000 Henry's were manufactured in 1860-1866, and around half of them are believed to have been used by Union soldiers, mostly purchased by the men themselves, some using reenlistment bonuses. "That damned Yankee rifle that can be loaded on Sunday and fired all week" was one of the most advanced firearms of the war. After the war Henry rifle subsequently saw hard use in the frontier west.
