I just recieved this blue porcelain 2/Um Italian Insulator. They also have been produced in the larger 1/Um style.

Thanks to Noro Coppo, she has told me that she found the blue Um's at Roma Fiuggi Railroad and on walls of a church in Genoa. Also, she has once seen the blue Um on a farm in Piedmont and another one in a small village in Tuscany.

This insulator is in very good condition.
