[CR]Unusual Zeus Triple Crank set on Ebay 260182969117

Zeus made several different milled/slotted crank sets during the 70†™s and 80’s.What is interesting about the one on Ebay is the na rrow width of the milled slot as compared to what is referenced in the US
   Zeus literature; also the milling work on the spider is not common.Refer ence http://www.wooljersey.com/gallery/broderir/Catalogs-Posters/Zeus/1 976-01.jpg.html Could this be a Europe only version? Scott Edrington San Deigo CA
