This particular is from Rubicon Models. It's a pretty amazing kit, as it contains enough stuff in it to build any of 10 different variants, ranging from the original models used in the SCW, through flamethrower and command variants, to versions with two turrets. As my focus is on Operation Barbarossa, I chose the M39 version with a 45 mm gun in the turret.
In What A Tanker games, we've learnt not to underestimate these older, smaller tanks. Even though they aren't packing the heaviest guns or armour, they still have enough power to take out (or at least hurt) the other tanks on the table. It can be a nasty surprise for one's opponent, after focusing all his attention on the T-34 or the KV-1, to be knocked out by the little T-26!
