I was told this was a High Voltage Insulator.
It is 11-11 1/2" Dia. x 7" High
on the top it has the #314A and on the side it has 407 with a "B' in the center of the "O"
Don't know what the value is but is the biggest I have in my collection.

    Quite possibly:
    "B in a circle: Found under top skirt. These insulators were made in Europe (Italy?) and used on lines in British Columbia. Don't confuse this rare marking with the relative common Ohio Brass markings, which is a B inside an Oval."

    Is yours a B inside a circle or an oval?

    See 4th picture, it looks to be an "O" broken into 4 sections with a "B" in the center.
    Hope this helps on identifying this.
