Like so many of the early war contractors who intended to produce US Model 1861 Rifle Muskets, the newly formed firm of Sarson & Roberts appears to have had minimal gun manufacturing experience and hoped to secure the majority of the parts necessary to build the guns from other makers and simply assemble the guns from those parts and then deliver them to the Ordnance Department. The firm initially received a contract for 25,000 guns on August 3, 1861 at the price of $18.50 each. The contract was subsequently reduced to 20,000 guns on June 17, 1862. At that point no guns had been delivered by the firm. The first deliveries would not be made until November of 1862 and from that time until November of 1863, only 5,140 of the guns contracted for would be delivered. The delivered guns ranged in quality from 1st Class, which were paid for at the rate of $20 each to 4th Class, which were paid for at the rate of $16 each. This contract resulted in the fewest deliveries of completed arms of all the contracts that were let for M1861 rifle muskets during the war, with only James Mulholland delivering a similarly low number at 5,500 total completed guns. This is for all practical purposes the rarest of the US Model 1861 Contract Rifle Muskets produced for the Ordnance Department and appears to be all correct. {ANTIQUE}
