Brett Horton recently supplied a list, provided by Eddy Merckx, of the bikes he (Merckx) rode; list below. The list does not mention Confente bikes.
In the Confente history pages (thanks Chuck Schmidt for the links) at http://www.bicycletrader.com/
So, maybe when someone meets with Eddy they can ask him about this.
