For your consideration, here is a Brown Ceramic Long 4 Hole Insulator Base. I think it is an insulator base anyway. It measures 8 1/4 inches long and 2 1/2 inches tall. It has a cardboard base.

It has some wear on it. There is a white spot at the bottom, on one long side where it looks like it was chipped or had a wide scratch. The cardboard base has some stains on it. Item pictured is the actual item up for sale and comes from a non-smoking household. (112.151h-2.11bb)
