wheelbase, manufacturers?

The most common trucks in the 1950s were plain journal ASF A-3 Ride
Control and Barber Stabilized S-2.
Wheelbase was 5'6" on 50 ton trucks,
5'8" on many 70 ton trucks. The ASF A-3 design was developed by
American Steel Foundries and the Barber S-2 originated with the
Standard Car Truck Co., but both designs were licensed to a number of
other manufacturers.

Mr Hendrickson, would there be a source for photos of these trucks?

Not being that knowledgeable with what they look like it would help in locating additional photos and the trucks in H.O scale.
