To pick up on that thread from last week and throw one more data point at the question of where FB hubs were made, I cracked open a set of NOS FB Extra Lusso hubs, which had "Made in Italy" stamped on the shell. The cones are marked 1955, so at least this model appears to have been made in Italy during the mid '50s.
