Marcus and Dale, This is an interesting topic on seat stay tops. As far as frame builders casting seat stay plugs into the seat tube / top tube lug - this technique has been practiced as early as the 1930's. I once owned a 1930's Bianchi frame, minus the paint. You could clearly see the brazed joint below the bullet shaped seat stay top and how it was part of the lug. The De Rosa frame in question is definitely from the 1970's. I have a 1973 De Rosa with the same features. Cheers Neil B. Seattle WA.
