This is my confused display of Italian insulators and some electrical devices. The purple insulator is a Fidenza 2D, there are two Miva BT2-CA in dark and light green, a FPL spool, a Pyrex 2-1920, a "frog" in light green (unmarked), two large bells from Roma-Fiuggi railroad (see the other pic for details), a little busbar insulator, a Ginori 2UM. You can see an old three-pole switch mfd. by "AVE Interruttori" in 1955, a rotative switch from USA, a push-button switch called "peretta" and an old porcelain lampholder with a 150W Na discharge lamp.
