Ok now I see the rear hub. Why would they have two generators?

Could it be a drum brake hub?

They sure did odd things back then!

I had a mens' Phillips that was probably 1953 or so. it was about 15 yrs old when I got it, a bit battered but working perfectly. I rode the heck out of it for about 5 years, then got a Falcon 531 bike - straight 531, and Campy Gran Sport derailleurs.
