I had/ have white industry hubs. http://www.bikepro.com/products/hubs/white.html
Quality wise I'd rate them only as ok. Front 1 seems fine, just replace the bearings, although the grub screw is a pain. (incidently david baker used this front hub for years
The rear 1 is very light. Thats probabily my only positive thing to say about it! The early hubs used copper leaf springs, waay to fragile as I found to my cost when the freehub died middle of dartmoor. found some wired, tied the spokes to the cassette & fixed gear all the way home.
Bearings also didnt have an axle spacer to pre-load the bearings (I had 1 made). Apparently later models used tougher "pawls" than the copper of the originals, which may last longer? (my mate carlo has some on his Funk which are still working fine, although he does like 50miles a year ;... & no the Funks not for sale!)
I'd date the hubs around 94/95
shortly afterwards the cranks had OEM copies made by sugino I believe, which in reliability probabily means that the suginos worked better than the originals.
