FYI - it was Hot wheels that made a D-50 die cast - 3 different colors - red with graphics, blue with graphics, and white with flames. All are from the Hi-jackers series with real rider rubber tires and were made from 1980 to 1985. I have managed to find all versions of these - the white one with flames is the hardest to find. There is also several versions of our 1st gen d-50s as a 1/25 scale plastic model.
