The Centuri Professional Firing Panel - CLICK HERE
It had an aluminum case, a safety key that turned and a red arming light. This wasn't just a "controller", it was a FIRING PANEL!
But . . . at $14.95, I could buy a few rockets and engines. It wasn't a necessity, I already had working Centuri and Estes controllers.

From the outside the controller looks simple and sturdy. You can see the black "crackle" finish on the aluminum case.
Opened up, there's not much there. For $14.95 I was expecting more! These were probably assembled by hand, one at a time.
On the left of the brown cord is a strain relief knot inside the casing.
