Well, it turns out it was a different make, it’s a ‘100 series’ by a company called Gerbing. Looks like they were around years ago, but have since disappeared.
It looks like their spider is slightly different than most, and the only ones around look to be new old stock. So I think I’ll replace the hubs and spider as a unit.
LOL! My wife of nearly thirty years.. committed before we married that she would NEVER say:
"I told you so!"..
Instead?
She smiles and says: "I HAVE told you!"
AFAIK, Gerbing's line was acquired by T.B. Woods, which was in turn folded into Dodge (or had been, already), which AFAIK is part of ABB/Rockwell Automation along with Baldor-Reliance, Dodge, Master, & c. these days. NEW spiders MAY still be stocked, at least as NOS, and at lower risk that the eBay dice-roll, ex:

Lovejoy, OTOH, is now a Timken property, and Timken is owned in turn by someone else (SKF?) who in turn..., etc.
Harry Timken probably known as "pinwheel Harry", other side of the pale, he'd be spinning in his grave at such a high velocity over that series of insults. To the good, he HAD made bearings of a grade to support that sort of activity...
