The tow truck is mostly wooden, with wooden wheels with painted on
details. The towing part and the open cab are made of plastic. The hook
of the towing part is a thin strip of metal ending in a loop. The headlights are just a couple of metal studs. The driver
is just a head, and moves his head in time to the wheels, in the same
manner as those with the early firetruck.
This piece in fact is very
similar in style to that firetruck. I think the set came with a small one seater car,
just like those that came with the Parking Ramp
Service Center, but possibly without a gas tank hole.
