All of the single face heads would have had remote controllers on the street. Some of the early fixed 4-ways came with internal controllers mounted on the bottom plate, or in the case of Eagle, in a 4th section at the top of the signal.
The Chapel Hill heads generally look pretty good when they come off the street unless they were in a terrible environment. Most people just put an extension cord on them to light them up. If yours is powered by an extension cord, it didn't operate from a remote controller except on the street. You'd need a four conductor cable to remotely control the signal.
As Nick said, this is a knockoff of the Type R. Chapel Hill made a pretty sturdy light for a poly signal and one difference from the Type R was that C-H used two door latches instead of one to keep the signal dust and moisture tight.
The LTG sequencer is good as is the one made by Joez Garage. They are relatively simple to wire. Just take your time and follow the instructions if you're not used to doing this stuff. Leave the sockets wired to the terminal block, one colored lead per terminal and all the white neutrals together, then with some 14 or 16 gauge wire you can connect between the terminal block and the controller.
I prefer 40 watt clear "ceiling fan" bulbs for indoor displays. 69 watts can get pretty harsh and the optics on these C-H signals are pretty good.
If you don't have a lot of signals in your collection yet, this is a good one to get your collection going.
