Just finished painting this one, as part of the review that I'm doing of the MiniArt kit. I don't have the references to comment on the total accuracy of the kit, but comparison to photo's are very favourable, and according to Terry Ashley on PMMS , where he reviewed the SU-76M Soviet Self-Propelled Gun w/Crew there is only a possible issue with the length of the barrel.
Painted with Vallejo "Russian Green" for the base, and used Vallejo "Dunkelgelb" for the camouflage. Not weathered as yet, because it is going in a diorama...

Cheers
Henk
