Structo was round before 1919 building
construction builder kits, but changed to automobile build kits around
1919. from there the company progressed to many different automobile
toys up to 1974 when the company was sold to Ertl and even then the toys
enjoyed popularity under the Ertl name for a few more years.

with as many numbers as I could find over the years. There is a timeline
section that show the models available for years from 1919-1975 with
descriptions. Enjoy the guide for what it was intended, a look at
Structo through the years. As with any human endeavor there are mistakes
but I have tried to be as accurate as possible.
