Assembled the crankset. Had to get "new" chainrings as the large one was wasted and small one was not even campagnolo. Got them both from fellow retrobike forum members. Thank you again!
Also got a new set of nuts. I was missing one and other was a bit bent.
Grease the bolts and tight'em down.
Couldn't help myself and mounted the pedals and dust-caps just to see how it looks!
Yes, that is were the Champion Mondials often had the size stamped. With earlier Champion Mondials the butterfly mentioned size and rear spacing on the back.
