I own the model from 1970! He was one of the first years in which the models Roco Minitanks were sold in Italy. I had seen the original in the US military base in Vicenza. After more than forty years the mold has never been updated and it is a real shame. Roco could at least replace the wheels (as it did with many models). I know of other companies that do this 1/87 scale model; recommended only if necessary.
