This is the first EVER "old" toy car/truck I have dug that was 100% complete. It looks like it is from the late 50's? It's Pressed steel, with no markings. Kinda cool don't ya think?
It's not pressed steel, but it's made of "Pot" metal, a zinc alloy (think Matchbox cars). Most likely it dates from the 1960s. They were made of several companies, but creskol is probably right as TOOTSIE made the most of these.
