Hilary,
Thank you for clearing that up. Was it always listed as that model number? It seems Stronglight's designs borrowed bits from previous designs and gave them a new model number, as an example, the model 57's arm is carried over to the model 63 with new chainrings, then the arm is redesigned and called the 93 using the same rings as the 63.
