Ok Thanks, it all ties together. I had no idea that freehubs were available as early as they were. ("Apres moi, la deluge") The hubs are Shimano 6400 series as were the rest of the parts, on a Gios Nuovo Compact, except for the RD which was a budget Shimano unit with the pie plate size lower jockey wheel presumably to expand the potential gear range. Was thinking maybe a Victory group...on a Red Frame.
