Manufactured 1861-1862, some estimates place the total number of these revolvers produced at around 700. Records show that 536 of Allen revolvers were purchased by the U.S. government in 1861 and it is generally assumed that the revolvers purchased were this model. The purchased revolvers were issued to the 2nd and 3rd Michigan cavalry regiments, both of which took part in the battles of Franklin and Nashville. Some reports suggest some were issued to Company A of the 33rd Pennsylvania Cavalry. This example has the standard two-line address/patent marking on the left barrel flat and is numbered "148" on the grip frame, cylinder pin, trigger guard/loading lever arm, and inside of each grip. Each grip has the "BH", Benjamin Hannis, government inspector cartouche. The revolver is pictured on page 107 of the included book "Ethan Allen and Allen & Wheelock: Their Guns and Their Legacy" by Paul Henry.

Good, showing mostly a mottled grey-brown patina with mostly distinct markings and some minor tool type marks on the barrel and frame concentrated around the cylinder pin. The grips are also good with moderate wear and some minor handling marks with mostly distinct cartouches. Mechanically excellent.
