So the US T1E2 Light Tank. This was one of a series of one-off prototypes, this one being built in 1928. Originally armed with a short 37mm anti-tank gun, it was re-armed with a 37mm Browning semi-automatic gun.
This was built from the Empress Miniatures kit.
I did break the supplied gun barrel, so replaced it with one made from brass rod.
The decals are from the Italeri 28mm M3 Stuart kit, I do have some suspicions about the US flag.
It does need some weathering.
