Children can imitate “panzer” warfare with a new toy tank of the track type that packs dummy guns and can crawl over ditches or small obstacles, and can be steered in a complete circle within a small space. Operated either by hand or small gasoline engine, the tank is large enough to hold the average size youngster. The power model runs at a fair rate of speed and, according to the manufacturer, five cents’ worth of gasoline will last four days.
