Original U.S. WWII M3 .45cal Grease Gun Display SMG by Guide Lamp Company

Item Description

Original Item: Only One Available. This is a fantastic BATF approved non-firing display M3 Grease Gun built using a dummy steel receiver along with genuine WWII parts. This wonderful condition Grease Gun was manufactured by the Guide Lamp Company and is complete with US ordnance markings on the left side of the magazine well: SUB-MACH. GUN / CAL 45 M3. This is the earlier version of the gun, with the "crank" style cocking lever, which was later removed from the design, as part of the changes to make the M3A1 version.

It is comprised of totally original WWII parts with the exception of the middle three inches of the BATF approved dummy receiver. Per requirements, this center section is solid bar stock, which has resulted in the display gun being somewhat heavier than the original. The original bolt has been welded into the forward position inside of the receiver, and can be seen under the ejection port. The barrel still unscrews, and has not been deactivated.

This is a BATF approved non-gun making it 100% legal for sale, trade and ownership within the USA. Comes complete one 30 round magazine (high capacity restrictions will apply), a telescoping wire shoulder stock with integral magazine loader, and fixed peep sights.

Its steel stamped 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 dummy gun 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.
