So I went to my Stonglight 57 and saw that
it does NOT have the Verot-Ferrin stamp (http://www.flickr.com/photos/8210984@N06/2614811051/) drive arm has a Stronlight-only oval (http://www.flickr.com/photos/8210984@N06/2615638118/) non-drive arm has a MARQUE STRONGLIGHT DEPOSEE oval chainrings attach with 7mm bolts (http://www.flickr.com/photos/8210984@N06/2615640420/)
The recessed nuts on the chainring bolts on the $898 ebay (140242882562) Stronglight don't look recessed.
The seller does not mention what type of Stronglight crank it is. Could it be a 63?
Are there any obvious marks on a 63 that distinguis it from a 57 other than the bolt diameter?
