Read all the threads about Sugino messenger cranks, there's a ton, so you will know ALL about 42mm and 45mm chain line and chain ring on inside and outside of the spider. If you care about straight chain line.
I had a vintage road double Campy crank and it worked great. Used the small chain ring with some stock Pista Alex wheels. Also nice was the Campy BB. Not the sealed cartridge type but vintage. It was smooooth.
I got new shorter chain ring bolts so the 1 chain ring would tighten up properly.
