To those interested. Steve's cabinet was used to house a small Eagle EA-74 mechanical controller. These were made and used in the 1940s. The EA-74 controller didn't use motors, it used magnets to turn a dial which in turn advanced the cam drum and changed the lights.
EA equipment is rare and usually in poor/unoperable shape without significant restoration work. I suspect thats the reason this cabinet was gutted.
EA series gave way to the famous EF series in the 1950s. EF mechanical controllers lasted until the 1970s. They used motors to drive the dials, and were the most popular and durable mechanical controller.
These were made when Eagle's name was "Eagle Signal", the Eagle Signal name lasted till 1997.
EDIT 3/13/11: Here's a 1945 advertisement for the Eagle EA Controller

Your welcome, and yes I do. My buddy Jeff has one.
This is the original EA-74 controller that goes in those cabinets. The dial timer is on the front of the cycle unit case inside. Inside that case is the cam drum and magnetic discs that advance the dial and cam drum to change the lights. Each light has a cam. The mechanism near the bottom right, is the flasher mechanism.

Here's his EA cabinet from the front
This is the cycle unit dropped in the cabinet to access the guts.
Here is a picture of the magnetic discs, gears and brakes
And this is the cam drum in the cycle unit.
