Approximately 5,000 First Model Maynard carbines were manufactured c. 1858-1859. "If the 1859 production ceased between serial nos. 1600 and 1900, and if production on an annual basis reached 150 arms per month during the period from January, 1860, to April, 1861, arms within the serial range from approximately 1800 through 4100 (give or take 200) should be in the range that saw Confederate service" according to Howard M. Madaus in "The Maynard Rifle and Carbine in the Confederate Service" in the American Society of Arms Collectors Bulletin No. 52 from 1985.
