Perhaps you are asking yourself why I have written the word "intact" on the title.

Because these big multiparts (four shells - three pieces) manufactured by Ginori in the first decade of 1900 for 60-70kv were too much defective and almost all of them were replaced after few years of service. For this reason, nowadays they are almost impossible to find intact.

[Update: these insulators have been produced from the '10s to the '20 probably for replacements.]

Another very important model added to my collection.
