I dont think that the VVS had the Red Star ever on just one wing though, it would be both, or neither. If they overpainted a US star/circle on the left wing with a VVS Red Star...they would also have a Red Star on the right wing. Same for the undersides, both wings would have stars. Only the USA had markings where just one wing had them, the UK, European, Russian, and IJ did not do that.
