Mark,

Not sure about the one with the spoke slots, but it looks like it would have a brake drum riveted to the opposite side, it's not Indian. The one with the threaded hub is Indian sidecar. Looks like Timken races so that would be '28 through WWII non brake sidecar hub. The sidecar brake came out as an option in 31 and I believe was still optional through the war.

Thanks for the ID on the Indian hub.
On another forum, someone suggested that the spoke slot hub may be British.
