Original U.S. WWII M3A1 Grease Gun Parts Set by Guide Lamp Compnay

Item Description

Original Item: Only One Available. This is a fantastic condition M3A1 grease gun parts set by Guide Lamp Company complete with US ordnance markings on left side of magazine and serial number 108516. It is comprised of totally original WWII parts. It is offered complete with the exception of the receiver making it 100% legal for sale, trade and ownership within the USA. Comes complete with flash hider, one 30 round magazine (high capacity restrictions will apply) and magazine loader. A telescoping wire shoulder stock, fixed peep sights, and all steel construction made this the must less costly successor to the Thompson and Rising sub-machine guns of WWII. It has an interesting safety mechanism that when the bolt is back and the ejector port cover is closed, a tab on the cover holds the bolt in the rear position, even when the trigger is actuated. One must open the ejector port cover in order for the bolt to move forward and fire. We haven't had, or even seen, a Grease Gun parts set in nearly 20 years, and we expect it could be another 20 years before we get another. Act now or be sorry later!

The M3 submachine gun, also known as Grease Gun, was developed as a cheaper war-time alternative to famous Thompson M1 and M1928 submachine guns. The basic requirements were set by US Ordnance Corps in February, 1941. George Hyde and Frederick Sampson, working together at Inland Division of general Motors Corp developed a prototype, which was designated the T20. The T-20 was a very simple weapon, made mostly from steel stampings. In November 1942 T20 was tested against several other prototypes, and was found superior to all other contestants. Late in 1942 the T20 was recommended for adoption, which followed in 1943. Combat use of a newly adopted M3 submachine gun showed some problematic points in design, most notably in the failing cocking mechanism. The problems were solved by elimination of this unit in 1944 when a further simplified weapon received the designation M3A1, and served with US Armed forces through the later part of WW2, Korean and Vietnam wars. M3A1 was issued to US tank crews all the way up until 1980s.

M3 submachine gun was a full-automatic blowback-operated firearm that fired from an open bolt. The receiver was made from steel stampings. M3 featured spring-loaded ejection port cover (which also acted as safety, locking the bolt when it is closed) and crank-type bolt retracting (cocking) handle at the right side of the receiver.
