This insulator stole the show. It's a green wide-grove columbia! Wow, what luck and it's loaded with amber swirles. The insulator does have a crack circling the dome and extending up into the left ear. I've determined that this is a manufacturing defect (i've got many brookfields with this that you can tell the cracks are as old as the insulator) that came about form two pieces of metal (one looks like a neail and the other is a ???) lodged in the left ear between te eye hole and ponhole. Quite an insulator, i now own 2 columbias which is more than i could have ever hoped for when i started collecting insulators.
