They are based on the designs of Dr. Edward Maynard, a dentist and inventor from New York and Washington, D.C. Approximately 20,000 of these Second Model carbines were manufactured in 1864 and 1865. Some were delivered late in the war and were issued and used by 6th, 9th, and 11th Indiana Cavalry and the 10th and 11th East Tennessee Union Cavalry.
