See first photo for comments.
6/9/10 - I received the following information from an ICON member in Italy. Thought others might find this of interest.
I really enjoy your pix and want to explain that the 1st photo shows a LV line with ordinary B 100 UNEL 38112 aqua glass insulators, the MV line is very old (8kv?) with brown 2 shells pintype insulators especially designed for local railroads and white small PADERNO types. The aqua glass discs are replacements of other insulators. The pole with white bell types is a typical pole of the '50s, equipped with old TYPE 2 (or B 100) and some strains called "bozzelli".
