Not quite sure what to call this bugger but upon looking it up it is found to be a rather big Westinghouse insulator of SOME sort. Big brown porcelain and embossed with a early 1900 date, it is a VERY unusual piece and heavy.A unique addition to a collection of bushings or other oddity insulators. Please email me with postal code for a ship quote. Shipping will ~probably~ be in the $9-$12 range. $13 plus shipping.
