Ya I'd love to make a cutaway diagram of it for posterity, but it's being used for a resto project I'm working on, an all original '39 Elgin girls bike, my neighbor's mother's childhood bicycle.
Besides, my budget doesn't allow me to to cut up parts like that. I think if I had 15 hubs just like it I STILL wouldn't cut one up because I'd have a use for every single one of 'em.
