Recently, digging through my stash, I pulled out quite big box with with 30N6E1 radar vehicle from S-300 PMU (SA-10 GRUMBLE) rocket system. Model is made by Belarusian company PST. It contains 197 parts and measures 20,46 cm when assembled.
Plastic usual kind for PST, of mediocre quality. Clear parts quite good. Kit contains 2 types of tires - rubber and plastic ones (2 halves each).
