Could be the original NX-73 before flight and belly landing in the field. I would have to go to the garage to look it up, but then get distracted and not finish any of today's projects.
Soviet armoured railway diesel wagon type MBV captured by the Germans.
Self-propelled wagon MBV53 x 76,2mm KT (5) + 5 x DT + 3 flak DT (in 3 turrets of T-28) + 4 x Maxim + 1 x DT + 1 x flak quad Maxim 120 km/h365 shells and 10962+22000 rounds Armored trains of USSR
Why the plastic modeller? Any.. a cardboard , wooden one etc.. just a modeller and he doesn't have to be a good. I would say an average one could make a nice replic of the MBV D-2 diesel wagon without any trouble.
