In the rand mcnally encyclopedia of military aircraft, there is a plane in there called a MiG 5. It isn't the DIS however, and it appears like a MiG 3 with a radial swap. It has some differences from the MiG 3 though. The books mentions it being in service but having poor performance when compared the the Lavochkin la5.
I am wondering if anybody can provide more information, maybe another designation that is more widely known.
