After a visit at a flea market in Chiavari, 15 miles from Genoa, I got other items hunting with my friend Andrea (again). I got back home also a MIVA glass disc emb. MIVA DISCO 220, where 220 indicates the diameter in millimeters. Here you see a 1/1920 on its hook, and a couple glass MIVA T6 BIS. Another insulator, an indoor type marked V (vaccari) is not in the photo
