This great emerald insulator is a MIVA transposition, coming from a trade with my friend Christian. This insulator is taller than the MIVA INCROCI P. in clear glass. Only two of this type are known, and the big stick letters of the embossing date this insulator the earliest production. MIVA was settled up in 1909, in 1974 changed its name in BORMAVI and then in BORMA, and closed in 1999. It remains a great piece of history in the Italian glass tradition.
