Yesterday I got two insulators type MIVA M 318 CA in green glass: one had the upper shell badly damaged, the other one had only the upper shell sane: I worked using a hammer and an old screwdriver to remove the two inner shells and to cement the upper shell, to rebuild one piece: as you can see, after this dangerous work (for my eyes) I could admire a new (but ancient) insulator. The hardest thing is that MIVA used true cement to build its multis.
