Tedco Inc
Chances are you have played with a gyroscope at some point in your life. More than likely, it was a Chandler gyroscope.
For over 70 years the Chandler Company of Indianapolis, Indiana, produced and sold virtually tens of millions of gyroscopes all over the country.
In 1982 TEDCO, Inc. purchased the Chandler Company. Since then, the toy line has expanded and sales are now global.
