The Last Quadruplex

(Click on any of the images on this page to see a larger version)

This is the last and most advanced model of the Quadruplex radio control systems – the CL5. Don Brown took this transmitter off the production line and kept it safe for over 4 decades, before autographing it and sending it to us. We don’t know if this was the last CL5 or an earlier production unit.
