The tank being offered, light tank M3A3 Stuart, serial number unknown, was built by American Car & Foundry Company (ACF). It is one of 62 M3A3's known to have been built with defective armor. These M3A3's were kept in the U.S. during World War II as training vehicles. In order to make sure that these vehicles were not deployed to combat units, the words “For Training Only” was welded onto the hull sides. Currently, this vehicle and one other M3A3, that is located in Virginia, are the only known survivors of the defective batch. This vehicle needs a complete restoration inside and out. It appears to be mostly complete. Tracks are usable.

The M3A3 was developed per an April 1942 request by the Armored Force for an M3A1 to built with a hull similar to that of the M5 light tank. A pilot model was built using welded homogeneous armor plate in a configuration similar to the M5. Instead of the twin Cadillac engines of the M5, it retained the radial engine of the M3A1. The vehicle was then designated light tank M3A3. It had sloping front armor like the M5 with individual roof hatches for the driver and bow gunner. While the M5 had vertical hull side, the M3A3 had sides that were sloped 20-degrees from the vertical.

The turret of the M3A3 was larger than that of both the M3A1 and M5 as it included a large bustle at the rear. This allowed the radio to be mounted in the turret near the commander as opposed to right hull front, next to the bow gunner. The M3A3 was equipped with the same 37-mm M6 cannon and co-axial .30-cal M1919A4 machine gun in the turret as the other light tanks.

The first production M3A3 left the assembly line in September 1942. Full-scale production began in January 1943 and continued until September 1943 by which time 3,427 M3A3's had been produced. Used only for training by the U.S. Army, the M3A3 was exported in great numbers via Lend-Lease to the UK, France and Nationalist China. In British service, it was named the Stuart V.
