This is an old drawing of a Paderno manufactured by Richard-Ginori around 1910 circa.

Very interesting is the wooden bracket were this Paderno is fixed on. This confirms the old age of this type of insulators because in Italy (differently from US) wooden poles for MV and HV were used only in the late 1800s, early 1900s.

Update: the real Paderno of this drawing is this [[id=572616570]]
