Colnago did make a "Competition" but I am not sure if it was a model or a different line altogether. As far as the Saronni badged bikes they weren't built by Saronni they were a Saronni model built by Colnago, they also had a Roger de Vlaeminck model.
These were the ones with eh RdV scroll in the fork crown and on the drop outs? You may know a fellow in North Van who has one... I meet him once, and the story was that the bike was made for Roger but colnago was short on an order and so put that in it... He also had a De rosa or some other brand (i forget) with the RdV in the fork grown...
