This Prop-Rod car
was one of the earliest models produced by L.M. Cox Manufacturing. For many years
the models went by the trade name of Thimble Drome, but later were know simply as
Cox models. It was featured in magazine advertisements as early as 1961 when it
appeared in American Modeler. The Prop-Rod came it a Babe Bee .049 engine that had
an inverted cylinder. It was designed to run either on a tether stretched along
a sidewalk, on a tether mounted in the center of a circle (see video below), or
it could just run free. These couple photos were captured from an eBay auction a
while back. The Prop-Rod was a little over 12 inches long and 6 inches wide.
