This listing is for an Ertl International red toy tractor.  It was made in Dyersville, Iowa, and the underside has the number ‘1733’ stamped on it.  The tractor is probably from the mid 1970s to early 1980s, based on when I had access to these.  I’ve seen others with wide rear tires.  These are thinner.  It is steerable - when you turn the wheel, the front wheels turn.  

I am unsure of the scale.  Other listings with similar-looking tractors say ‘1:16’ scale, so mine is likely that as well.

Measurements -
About 8” long front to back
About 4.5” wide from outside of rear tires
About 4.5” tall to top of steering wheel

I’m also unsure of the exact material.  It’s metal, but I don’t know if it’s die-cast or pressed steel.

Condition - Lots of paint chipping.  Tires/wheels seem fine.  The tractor moves as it should when pushed.  See all pictures!
