Best comparison is to changing a bayonet mounted lens on a camera. Cassette freewheel. Very high quality, six speed era and competively lightweight for the time.
I suppose the days were numbered as more gears and longer axles were soon coming, the weakness of axles stubs without outboard bearing hub design.
The fellow I acquired this from also 'has' a few cassette's for this in aluminum! Pretty sure its prototype or Regina show piece.
