| The very early Structo trucks first
appeared around 1924 and were not associated with the auto builder
trucks. Made from a 24 gauge steel they were light pressed trucks
without windup motors. Most were 17 inches long but some were longer.
Wheels were made of stamped steel and were painted with red hubs and
white balloon tires. Simple design with a curving hood made from one
piece of metal. Easily distinguished from the next generation by the
absent of a piece of metal that sticks up from the cowl just in front of
the cab of the truck. This truck was replaced around 1930-31.
