I have listed on eBay some wool jerseys from the 1970s and a ZEUS (Spain) crankset the is milled and drilled (the one with the slots in the arms that go completely through). This is the crankset that was used for a photoshoot that Bicycling magazine did for an article on light weight parts a few years ago. Pretty amazing looking crankset from the height of the "drillium" craze of the mid 1970s.
