The Eagle Manufacturing Company was established in late 1861 and received a contract to delivery 25,000 US Model 1861 Rifle Muskets at the rate of $20 each. The principles in the company were Henry Almy and James D Mowry. The firm delivered only 5,500 guns under the contract in 1863, before the firm was acquired by Mowry's newly formed Norwich Arms Company. Norwich would deliver the balance of the Eagle Mfg. Co. contract. Eagle Manufacturing was responsible one of the three smallest deliveries of US M1861 contract rifle muskets with Sarson & Roberts being the least successful contractor at 5,140 deliveries and Eagle Mfg. Co. and James Mulholland tying for the second least successful contractors with both delivering 5,500 guns. Eagleville marked muskets are particularly scarce on the collector market. {ANTIQUE}
