Anyone know anything about these S-works wheels?

[JSO]

I purchased a NOS set of Z-21 Pro rims each having perfect unpeeled S-works decals around the entire perimeter. They have M900 Hubs. I have since attached M900 cassete and Umma's.
The only online reference I have found is on a Japanese website depicting them on a 92 S-Works (with White hubs).
Anyone have a set? Any info would be appreciated.

Really want some of these. i have some of the Z21 rims, not the pro ones. They are very light.

Chris do you know of some for sale?
