Turning Target Controller

Need help finding someone to repair a non-functioning turning target controller or in the alternative replacing the controller. The non-functioning controller was built by Frank Thomas somewhere in TN.

Ed Hall, designed a turner built from a car wiper motor, maybe he will answer and give details.

I have repaired a couple of these many years ago, but it took me a bit to figure out the circuitry. I'm sure I don't remember much from those repairs and would need to start pretty much from scratch. I believe there was an individual that officially took over from Thomas, but that was long ago, as well. I'm sure I could come up with a repair, but I am quite slow with everything these days, so it would take a while. If you are not in a big hurry and are going to Camp Perry, it might be best to bring it to me there and I can look at it then, if you haven't gotten it fixed by Nationals.
