All of these trucks never made it to the production line.
I can date them back to the early 1980's.

All trucks are pressed steel construction with some plastic parts.

The only information I could find out was that the Bobcat Company asked the Nylint Corporation to produce these back in the 1980's, but production costs were to high and the project was rejected, it lasted until 1994 before Bobcat made another attempt to manufacture there first semi-truck and pick-up truck.
