Not being collectors but rather inheriting a collection of insulators, we have a question regarding one particularly odd insulator that we have. It looks to be an insulator that has been somehow fused with another identical insulator, however on close examination, it is obvious that this particular insulator was custom blown in this configuration. A comprehensive search has turned up nothing on this insulator or anything remotely like it. Any help would be greatly appreciated.

Thanks, Bo and Pinky
