Here Andrea, near Pisa on a pole of the old line Pisa-Firenze removing the TS 1 FP insulators by RICHARD GINORI (all dating 1948). No one of them turned off the pin, so we had to remove the iron pins from the crossarms. We got 40 insulators (approx.). The remaining insulators on the pole are damaged (not interesting for us). Note about the line: this is the line that connected the telephones of Pisa and Florence. I remember the line with all its wires, not over 25-30 yrs ago.
