The Open Top Bus Company. Children and adults are bound to like this enchanting memento of the bygone days in Yellowstone National Park. The "O" scale White Model 706 tour bus has been replicated with close attention to original detail. The die-cast metal body sports tires with the exact tread design of the original fleet. Other features, too, such as the "railroad lantern" tail lights, the gearshift levers, grab-handles on the seatbacks, and the four-spoke steering wheel are modeled exactly like those on the original bus. Die-cast and railroad modelers will be thrilled to add the 1936 to their collections. 2002.
