wagon wheel hubs I'd think--but could also be some hub off of an early-day type of wheel for a steam vehicle such as an early-day car or truck with wooden wheels or an early wheel hub for one of the smaller steam trains.
When I saw this hub, it rang a bell. Without seeing it in person, and judging by the pics, I think it's some type of automotive wheel. Excuse the quality of the pics below, but there were scanned from poor hard copies which were photographed upteen years ago. The pics are of our past 1928 Studebaker, and I refinished the solid oak spokes and pin-striped them so that's why your hub looked familiar. Of course, I did this many moons ago and I understand the memory is the 2nd thing to go. Breezie
I have a pic of the actual hub somewhere in this house, and if I can find it, I'll post.
