This is a 1/35 scale model of the Russian T-38 amphibious tank from WWII.
The model was made from the MPM reboxing of the Condor kit, and it came with a small fret of photoetched parts. It was built mostly out of the box. I cut open the turret hatch and replaced the 20mm gun barrel with a brass tube. I also added the tank commander figure.

The figure shows how tiny this tank was. It's a modified Tamiya US Army WWII tanker, made by replacing the head with a Tamiya WWII Russian tanker head and changing the arm positions.
