Moving in a little closer, one can see that these purple Fidenza 6315s have suffered an ignominious fate. Hope some enterprising collector can rescue them before the rest get destroyed...

I've recently seen purple 6315s fetch as much as nearly $500 on e-bay, the more "normal" price for these is usually around $150, plus overseas shipping.

Perhaps some of these broken insulators can be "re-combined" into a couple of repaird good-looking ones...

6315: three parts / shells, 15KV rated. MIVA's equivvalent would be M 315 CA. Both are in the CD 376 family.
