Thanks for this helpful find.

Unsure what you intend by statement "crankset is correct"...

The subject machine wears an FB set and the catalogue page posted states machine equipped with a Magistroni set.

Found it interesting that the 1955 Model B linked to by [MENTION=272567]1987[/MENTION] is constructed with Juy ends marked BREV SIMPLEX which suggests them to be a product of Juy D'Italia since a French produced set would be marked SDGB if the manufacturer wished to indicate a patent.
