The company, whose full name is Ditta Stilo-Everest, was based in Turin in Via Martiri Fascisti (as reflected by some catalogs) also if in this advertisement is reported Card. Maurizio 14 and in this advertisement is reported Via Superga 25. There is no known foundation date, and the trademark is registered (Reg. Gen. N. 80254) only after the war (1947).
In the Paravia guide for Turin of 1948, in the fountain pen section, the "F.A.V. Fabbricazione Accessori Vari" appears at the same address of Via Card. Maurizio 14, but it is not clear (given the appearance of another address in a previous advertisement) if there is still a relationship with Stilo Everest.
It is not known whether this is a direct manufacturer or just a retailer, but in the models shown in those catalogs seems evident a remarkable similarity with the productions of companies like Montegrappa and SAFIS, and it's also reported a production commissioned to Giacomazzi.
