On occasion toy manufactures have been known to attempt to extend the use of existing tooling from previously successful selling items. This practice can result in increased returns from tooling expenditures and can also result in unusual variations. Such variations frequently became more appealing to future collectors than the original version(s).
Ertl did just that in the early 1950’s. They had produced an excellent die cast white metal Greyhound bus based on the 1951 model GMC. That bus was about 9.3 inches long and road on six black rubber wheels.
