That's the point - minimal hand labor equals more frames per hour.
The Casati has a three-digit serial-Nr. and a headbadge with a carat-stamp... i really don't think that frames/hour was an issue with that very frame
but it is of course a child of its time, when Microfusione-lugs were still quite new.
My own ranking of these 4 frames would be Appel - Merckx - Zunow&Casati , but all 4 are quite fine examples.
