Notes: "The war had introduced the submachine gun to many people who had not given it a thought before. As a result, many of them decided that there was a future in weapons design and manufacture, though several of them went into business without stopping to consider who was going to buy their products. The postwar years saw a plentiful supply of war-surplus submachine-guns on the market, and a design had to be either very good, very cheap, or capable of being supplied in very large numbers in order to compete. Few met this requirement.
One of the few which managed to survive was the Ingram submachine-gun. Gordon Ingram served during the war and returned to the USA intent upon making a submachine-gun for police use. In 1946 he produced his 'Model 5', so-called because the Army had already standardized their M1, M2 and M3 and were contemplating an M4. The Model 5 was a very simple design with the receiver and jacket made of seamless steel tubing, and with only three moving parts - the trigger, sear and bolt. Fitted with a wooden butt, had a 25-round magazine, weighed just over 6 lb. and was a simple and robust weapon. But in 1946 nobody was particularly interested, and the Model 5 never went past the prototype stage.
Nothing daunted, Ingram set to work to produce a new design, and in 1949 came the Model 6, which was put on the market by the Police Ordnance Company, formed by Ingram and three friends. Like so many other American designs, the Model 6 showed lingering traces of the Thompson influence, with forward pistol grip, finned barrel and wooden butt. It was, however, a much simpler weapon than the Thompson. The mechanism was the usual blow-back with differential locking and the gun was offered in .45, .38ACP and 9-mm chambering. The Model 6 was demonstrated to the California Police Chief's Convention in 1949 and subsequently sold in some numbers. As well as several thousand sold in the USA it was bought by the Peruvian government for their army and was later built in Peru.
The Model 6 was originally designed to fire only at automatic. A later model, still numbered 6, had a trigger mechanism which allowed single shots when the trigger was pulled back on stage, automatic fire when it was fully pulled back." - Ian Hogg

"The first P.O.C. submachine guns supplied to the Peruvian government were produced during 1951 in the United States by the Police Ordnance Company, located in Los Angeles, California. In 1952, production of the M6 started in Peru and is reported to have continued in very limited numbers until the late 1950's.
This weapon was produced within Peru under Ingram license. The P.O.C., as manufactured in Peru, is identical in every respect to the military model of the Police Ordnance Company Model 6 submachine gun produced in California. The Peruvian model was tested at Aberdeen Proving Ground in 1956 (this specimen was the weapon tested) and the result proved it to be marginal....The weapon fires from the open-bolt position and is primarily composed of seamless steel tubing which requires a minimum of equipment and special tooling to produce." - Thomas B.
