i just picked up the AMG Polikarpov R-5 NKVD (USSR Border Troops) kit in 1/72 scale. The painting instructions were cryptic at best, relying on b&w illustrations. Photos of the VVS R-5s showed a natural metal engine compartment with green top and light blue undersurfaces. Were the NKVD R-5s white or silver doped aft of the engine compartment? The instructions are not clear? Bal’shoe Spasiba for any help……
