The MJ system employed a standard control head design,
developed and manufactured by Secode, all
of which were labeled ITT inside and then labeled with the appropriate
manufacturer's logo on the outside faceplate, such as Motorola, GE, Bell System, left blank, or
with a generic logo saying "Radio Telephone" (see example below.)
The control head is interchangeable among all manufacturers of the equipment,
even though the actual radio packages differ greatly. The cables for
the assorted brands of "MJ" equipment are also all interchangeable, so
that a GE head and cable will work perfectly on a Motorola RF package, and vice
See here a brilliant description from Mr. Geoff Fors:
My name is terry. I live in the CA area. I am just about to open a western electric (ma bell and Motorola museum) I would love to display the MJ Motorola control head to show the youth of today what took place in the past. I'm not sure what the cost would be today without the equipment package to along with it. Please let me know if you would be interested in donating the unit for prosperity or a amount you might be interested in selling it for.

These were wonderful item. I had a working unit for over seven years. When analog was phased out by the government it went to the way side. Not sure on the price anymore. I am about to open a Motorola/Western Electric Museum in CA. I would love to have this on display. Please let me know.
