Very early models of that pole only had one light that was between the globe and the cylinder. That would light both the cylinder and globe evenly, but very weakly. Since your globe looks like it's lit pretty well, I'm guessing it's "supposed" to be a two light as it has a light going into the globe but nothing into the cylinder.
The light that Coheley shows is what you need. You can call Marvy and tell them you have a Koken 23 (6" glass) and they'll know what you're talking about.
I have MANY of those wind up motors. What do you need to know?
