Manufactured in the 1960s, the "S" prefix Ithaca Model 37 shotguns were intended to supplement the U.S. government's then-dwindling stockpile of World War II surplus riot and trench shotguns, which were in high demand in the jungles of Vietnam. Single brass bead sight, with "FULL" choke marking and 2 3/4 inch chamber. "P" stamps are present on top of the chamber and receiver, with matching serial number marked on the barrel and front of receiver, and "U.S." marked on the right side of the receiver. Some of these shotguns are said to have been given to local police departments during the Vietnam protests and riots. "BPD" marked on the left rear of the receiver, and "P3421" marked on the right rear of the receiver. Large "L91" carved and painted on the right of the buttstock. Fitted with a 16-groove forearm and smooth pistol grip stock with serrated plastic buttplate. 14 inch length of pull. Includes an olive drab green canvas sling.
