What beast of a Freehub is this?

a friend was struggling to extract what he'd thought was an 8S Freewheel.
after much struggle a FH body revealed itself.
but neither of us have ever seen anything similar.
a triple step down Freehub?
it might be cheap as a anything but we are both still curious as to its origins . and purpose

Looks like a threaded on freewheel with the cogs removed. Note the splines for a freewheel removal tool.

It's a freewheel, the extractor splines are clearly visible, just a bit further back than on a 6 or 7 speed

I'm more impressed that you managed to get the lockring off.

There are no known off the shelf tools that remove those and similar variations of lockrings on freewheels.

Uniglide Freewheel? I had one of those on an early 90's Giant 6 spd road bike. Bill Kaupun, a knowledgeable member here could tell you exactly, I'm sure.

It's 8 speed, so unlikely to be Shimano or very old.

Who?
Never heard of a UniGlide Free Wheel. Just UniGlide Cassettes.
That's just a Free Wheel.

Seriously? The MF-62nn (Shimano 600) and MF-72nn (Dura-Ace) freewheels were the first to get the Uniglide twisted tooth treatment, and IMO are among the best best freewheels ever put on the market.

That's just a Free Wheel.
The remover spline pattern is consistent with a Uniglide freewheel, but that extractor format became standard across all Shimano freewheels, even today. There ought to be a model number under the grime:


The lockring indicates it is not one of the early Uniglide freewheels; I suspect it is a later Hyperglide model. IME, mechanically not as nice as the original Uniglides, but the Hyperglide tooth profiling makes for nice shifting performance and the low price makes it easy to consider them as consumable items to be replaced when problems arise.
