The majority of the Whitney production of long arms during the American Civil War were of his numerous "Good & Serviceable" arms which were "not subject to gauging" and were not fully interchangeable. However, he did receive two contracts from the US Government to produce fully interchangeable Model 1861 Rifle Muskets, one for 40,000 guns and one for 15,000 guns. Due to his facility being tied up producing US Model 1861 Navy Rifles ("Plymouth Rifles") and numerous state contracts, particularly for Connecticut, he did not deliver any guns under that contracts in a timely fashion. In the end the two contracts were combined and were reduced to 25,000 gun, of which Whitney delivered 15,000 between 1863 and 1865 with the bulk of the deliveries in 1864. {ANTIQUE}
