This is an injection-plastic military vehicle model kit.
From the manufacturer:
The T-50 light infantry tank was built by the Soviet Union at the beginning of World War II. The design for this vehicle had some advanced features, but was complicated and expensive, and only a short production run of 69 tanks was completed. Furthermore, even before it was ready for mass-production, wartime experience invalidated the underlying concept of light tanks.
This kit consists of parts molded in clear, beige, and brown plastic, and includes decals and photo-etched parts. Completed model measures 149mm long and 70mm wide.
