These Shimano Sealed Mechanism (bearing) 36-hole hubs and quick release skewers were on my Mongoose IBOC Comp MTB I bought in/around 1989. They are in good condition, and I would've kept rolling with them but the rims were starting to wear out, so I replaced the entire wheels.
The FH-M452 rear hub takes up to a 7-speed cassette. It can also work with a single-speed cog and spacers.
One skewer spring is missing, but you can get one from a shop (probably free).
Sale is final. Buyer pays shipping. Thanks for your interest.
