I've heard the name, and I believe they also made saddles which were quite nice copies of the Unicanitor models.
I wonder if perhaps they were an affiliate or a subsidiary of "Zeus". I do have a couple quite nice Zeus copies of the first generation Campy 2-bolt Super Record posts, just as you describe, and indeed they too were very beauifully polished. As I recall, the Zeus products always sold for perhaps half the cost of the Campy originals - and they never broke.

They appear to be very well made, or at least very shiny, if a bit heavy. One is going on one of my bikes. This is another NOS stash I've been offered and know nothing about..."
