I saw one of this batch of vehicles at Beltring last week. It was in running order and was being operated by the "Friends of the Tank Museum" (from Bovington here in the UK). The interior had been repainted in white but the exterior had not been repainted and was still in a very thin and worn layer of the original Brazilian OD paint, but overall it had a light coating of surface rust. Sorry I did not get a pic.

Cheers, Ade.
