After a three hours walk in the wild, I found these two telephone insulators in pyrex glass, dating 1956: one is a classic type 2/920, while the second is a capolinea insulator type CAP. 1219. Both manufactured by M.I.V.A. for the TE.TI. (TElefonica TIrrena) telephone co. Sometimes it happens, you walk without searching insulators and then find them, suddenly. Nothing bad, not al all..............
