I do not have one of those closers (or lathe), but I have seen a few. You are calling the drive connection a gear. That is not necessarily correct. It might be a spline, of which there are many styles. All it really does is couple the spindle to the closer. Anything that would properly drive one part with the other would work. All that said, a company making lathes also makes and uses plenty of involute gears, so that is probably a good guess of what was used. But it isn't part of a gear train, it is essentially a spine drive, and does not need to be fancy at all...
