Some 20 years ago I found the tank in a “museum” of sorts north of London, more like a dump, but it was running. Via the War and Peace show I took delivery and shipped it back to the Netherlands.

The Stuart offered for auction is a M3A1 Hybrid and therefore likely a mid production M3. I has a late M3A1 turret without a basket. Also a manual azimure traverse and other interior fittings characteristic to a Hybrid. The round armor on the rear of the tank comes originally from a M3A1.

This particular model is in January 2024 equipped with a new refurbished Continental W-670-9A radial engine (carried out by BAIV). This Stuart is in running condition and drives and steers well.

Some bits and pieces are missing but it won’t take much effort to restore this tank back to its original condition.

This tank comes also with additional (spare) parts:

  • New (but rusty) steel tracks, French army
  • 6 Veloute springs fitting Stuart (original for halftrack)
  • Big collection of manuals for M3A1
  • Breech guard
  • 1 Bogie wheel assembly, 2 spare rubber “tires”
  • 1 Idler wheel assembly
  • Take out breech and gun parts


The first prototype was developed in July 1940 and it was adopted by the American army which launched production of the M3 tank in March 1941. The main modifications compared to the M2 light tank reside in the fact that the M3 Stuart has much greater shielding. Late production M3s were fitted with turret developed for M3A1, though without turret basket. These tanks were dubbed “Stuart Hybrid”.
The M3 saw service with American forces in the Philippines when the Japanese invaded in December 1941. Feedback from these actions led to improvements incorporated in the M3A1, which began production in May 1942.

In June 1942 a batch of 7 Stuart M3A1 were produced in Berwick plant of the Car and Foundry Company, among them was Stuart 5603. This was the second batch of M3A1’s and many parts were still missing, or hand produced. It is interesting to find a handwritten note on one of the fuel tanks with the production number, so these parts were handmade most likely.

Ready or not, the tank was rushed to the UK as part of the land lease agreement. No hydraulics for traversing the turret or stabilizing the gun were present, turret basket was missing and many parts were really M3, not the improved M3A1.

The British were not amused, how to fight in a tank like this, turret rotating with a small hand crank, not the big wheel from the M3 but only the backup for the hydraulic system, but with missing hydraulics. Interestingly The British thought it could serve well in Australia, where the tank served during the war. At time of decommissioning the tank was sent back to the UK, probably to honor the land lease agreement.

Although poorly suited to tank warfare in Europe, the Stuart tank proved effective in the Pacific. In New Guinea and the Solomons, the Stuart served in an infantry support role. Although the 37mm gun was not ideal, the small Stuart was much more practical for jungle warfare than the much larger and heavier Sherman that replaced it in late 1943. The M3A1 also saw service with American forces during the North African Campaign.
