It's got shimano 600 brake levers, the ones with the drilling, SR bars stem and cranks, suntour rear derailleur, Ritchey vantage comp rims on some silver hubs (miche I think), Kashima professional leather saddle... Apparently some of them weren't sold with the full shimano 600 groupset as the 1979 brochure claims as I've seen a couple going on ebay with the exact same mix of components as mine.
So almost all original components
