Hello tulippx,

Good to read information of assistance. If you explore those Atala & Lygie resource pages you will get to see what the bicycle's original fork may have looked like.

Readers often ask regarding headplate fastener holes on these mystery identifications. In this case it is somewhat moot as Rizzato did both metal headplates w/fasteners and adhesive transfer ones, both formats in the same era.

The firm had a third marque for their products which does not come into play here as it was employed only for an economy line. This was called Atlantica.

Will look forward to read what the experts have to say regarding the fork. The NERVOR steerer is strongly suggestive of a French origin although it could also be Belgian. Have you as yet checked its thread/dimension? One would expect an O.D. of 25.0mm and an I.D. of 22.0mm.

Best wishes with your researches.
