JL Cox & Son Pipeline Toy Trucks

Hello from Raytown..
This is what we were able to find on the toy trucks.
They were made and given to officers and close friends of the J.L. Cox Pipeline Co. in approximately 1952.
(no number as to how many)

There were several versions of the truck:
This one hauling pipe
One hauling a caterpillar tractor
An airplane that was similar to the one the pipeline company flew.

One of these trucks can be seen at the Raytown Historical Museum in Raytown, Missouri and one is also on display at the All American Toy Co. in Salem, Oregon.
This is all the information we have to date on this rare custom All American pipe hauler.
