Horace E. Dimick could not produce enough rifles to equip the entire regiment (Birge's Western Sharpshooters, aka 66 Illinois Volunteer Infantry). It was not beyond him to purchase guns from other makers. Per Bill Edwards (Civil War Guns), Dimick delivered 472 guns by April 27, 1862. A check of Ken Bauman's book, Arming the Suckers, has the Quartermaster's Return which shows the maximum of 538 Dimmick Target & Sporting Rifles carried by them was in the second quarter of 1863. By the 1st quarter of 1864, they had 71 Dimmicks, 206 Springfield rifle musket (1855-63) and 63 Austrian Lorenz.
