At least, we were told it's an insulator! It looks like it may have a high power application. This beast is about 29-1/2" tall, 7" across the top and 14" at the base, and I would estimate in the 40 lb range for weight, perhaps more. There are three pictures in all, so click on Next twice more and you'll get a look at it by our GMC Safari van, and a view up the "pinhole". As with the Ohio Brass Whatsit? we posted earlier in the week, replies privately or to ICON are welcome. Thanks!
