Fat 3" Brown Ceramic Insulator (Embossed) Vintage Lag Screw Style.  An insulator with potential...  Has some embossing on one side that we couldn't make out.  Ceramic portion measures approximately 3 inches tall with a 2-1/2 inch diameter base, lag screw portion measures approximately 2-1/8 inches long.  Insulator has a great retro shape but has at least two partial coats of paint of unknown type, sold as is.  Insulator is solid and doesn't appear to have any chips or cracks but can't say it's defect free because of the paint, sold as is, lag screw has some rust.  Listing photos show glare and shadows from lighting.
