Being that these were just over the fence, on the Naval base at La Spezia, I think they are protected from harvasting (if there even are any Italian insulator collectors) If you find yourself there, they were along side of the road, near the port on the way to the port called Portovenere

Updated info from Italian collector Nora Coppo: "Some U typed, extremely old and rare (it would be great to save these insulators)"
