Here’s one I would LOVE some catalog insight into.
Musselman, Eclipse, Corbin...looks like a bit of all of them, any insights?

I broke it down completely for your viewing pleasure.

A cam spreads the brass bushings into the interior of the hub shell which are kept in place by a spring steel ring.

Super cool.

Still plumbing the depths-
Thus far, no clues or leads.

It's surprising there isn't some kind of markings on this unit? At least in the pictures there aren't any visible. I guess I have a question... any idea what the thread pitch is on the axle, and is it possible there are stamping's or some other markings on the back side of the brake shoes or under the patina on the hub it's self? Or... on the brake arm some where?
Some of the machining looks crude enough it could have been a one off? The brake arm isn't finished as well as some of the other parts either? And, the finish on the inner hub is also rough..One more stab in the dark if the thread pitch isn't SAE could it be European in origin?
This seems like it would be a pretty stout brake for a standard bicycle? Maybe it was for a tandem or some other H.D. application? Again thanks for posting this, I second the appreciation for the great pictures!

Yes sounds plausible.... I can't remember where but I've seen pictures of ambulance bikes used in WW1.. wish I could remember where I found them... Hadn't thought about the Circus bike possibility.. Interesting.

I second Adam's thought that it is something.. interesting anyway?
@Beek I'm confused about the lack of mfg stamp but I looked it over pretty darn good and couldn't find anything. That said, I've missed text stamps before and only come across them after many a look. I may soak it in OA and see what pops up.

@bikewhorder yep this is a front hub I believe, no threading for a cog, for certain a non-drive hub.

Agreed.. and that brake might be strong enough to scrub off some of the speed.. did those early hubs and wheels use that gauge spoke? The brake arm slot for the cable barrel end looks larger than say an end for a bicycle cable end. So maybe your on to something thehugheseum..

its not motorcycle or it would be mine........right jesse?...lol....it is not a floating axle and the spoke holes are too small to be motorcycle, sidenote the teen era in the states was not super focused on brakes or good braking, riders decompressed/lifted a valve or had ignition cutoff switches which did the lions share of braking......the brake was more like a emergency brake and it better have been an emergency because they were not good at stopping

i wanna see some circus bike pics.....i also thought early on it might be some sort of cart hub but again the spoke holes too tiny, cool piece no matter what it is
