from a windmill manufacturer website, exploded view. (just one version of a
windmill motor, but i think most of them are nowadays covered and covered in
oil.)

i tried to find a pic of the head assembled but couldn't, maybe someone else
can.

I think you're correct except for the application. I suspect it's the
gear head for an old time water pumping wind mill.
That could very well be; it sounds a bit more likely than my guess.
Perhaps the strange right-angle box is some sort of an automatic shutoff
to stop the pump when the tank is filled. (Maybe it's not used with a
windmill, but wtih a gasoline engine or electric motor. Weren't most
windmill systems just a simple crank on the windmill shaft without any
gearing at all? Something like this would be a bit tricky to rotate to
get the windmill facing the wind, unless perhaps the pump rod also
rotated.)
I still like the elevator door opener idea, though; it has a certain je
ne sais quois that a pump jack lacks.
