^Thats a beautiful bike. Possible its Columbus SL or three main - Tretubi.

Also, I spotted a near new condition one but in blue metallic / Campy Triomphe. It was at a bike shop that was part of a large lot of 80's era fine bikes thru a donation / operative. Spotted the bike in the back before the shop owner serviced it and even then it looked great. He was planning to keep but apparently changed his mind. If interested, could guide one to it.

The Ochsner company is in Wheeling, IL.

As for the OP bike, had a chance to see it this last autumn. Gorgeous.
