Not A campy group set, but bits and pieces of them were Grand Sport. I know that Grand Sport was available in the 70s because I had a seat post and some other bits I purchased in the mid 80s. I know the Suntour isn't period correct, but it was available in the early 80s. I think it has a Cyclone FD and RD and shifters, of course Cinelli bars, stem, and saddle. Pics? He throw it out a long time ago.

I bet it was Beech since it was readily available through northern Europe.
