I saw a steel (shaft+steel) pressed-on-race style Campagnolo Con Sfere da 3/16" spindle on ebay this morning; see 280188816975. Seller is claiming said spindle application is for year 1959 cranks and or 151 bcd cranks; I did not think the Con Sfere's were that old. But hey, I could be wrong? I just flipped through every page of all of the Campagnolo catalogs, and unless I am blind, did not see the spindle that is for sale on ebay. I did see a similar one; it was a Super Record titanium model with the pressed on steel races.
I am looking for information as to the year of manufacture for the steel/steel Con Sfere spindle. I did wade through the archives but did not find anything short of a guy who said he pulled one out of a 1962 Frejus.
