Because of the losses E. Whitney suffered on his Model 1841 Rifles he was convinced he could not make a profit by making military long arms to the government's strick uniform gauging system. He, therefore, turned to an inexpensive series of long arms whose cost and availability to state militias would provide him a fair profit. The first models were a cross between the U.S. Model 1855 and the British Model 1853 rifle-musket probably because he wanted to make use of the parts & machinery he bought from the Robbins & Lawrence firm of Windsor Vt. when they went bankrupt. His later models more closely resembled the regulation Model 1861 Rifle Musket. He eventually did produce the Model 1861 for the U.S. as well as a "Plymouth Rifle" in .69 cal. In the above ad the top rifle is the 2 band Whitney Enfield Rifle. In the middle is the 3 band Whitney Long Enfield Rifle musket across which is the obverse of the 2 band rifle with the enfield ladder rearsight clearly displayed. Below are various Whitney revolvers.
