In 1861, the state of New York contracted with Frederick H. Grosz for the alteration of 1,600 Remington Model 1841 rifles for use with the M1840 angular socket bayonet, although the 1862 annual report of the New York adjutant general stated that a total of 2,180 Remington .54 caliber rifles with angular socket bayonets were in the hands of the state's militia regiments serving in the Union Army. Grosz alteration rifles feature a turned down barrel muzzle with a small square bayonet stud added to the underside near the muzzle and a repositioned blade front sight behind the turn-down area. Some of these rifles are known to have been issued to Federal units and New York 7th, 10th, 12th, and 192nd Regiments. Grosz alteration Remington Model 1841 rifles are described on pages 167-168 of George D. Moller's book "American Military Shoulder Arms Volume III". The lock plate of this rifle has the three line Remington marking and "1849" date stamped vertically behind the hammer. The barrel tang is also dated "1849" and the barrel is stamped "U.S./JCB/P" at the breech and "STEEL" on the left flat. Fitted with brass furniture including a patch box containing a tool and extra nipple. "U.S." and "40/E/40" marked buttplate tang. Includes an E. A. Crossman & Co. Newark leather sling.
