Here is a piece that is a pretty interesting variant I don't think I have seen before - insulator on the left.

It is a CD 280 HEMI [025] with tiny embossing and a larger then usual head. shell fracture and short stress crack on the back plus one missing drip and two flaked drips. A very interesting variation I have not seen before. The light aqua example to the right is for comparison only. $25 plus actual postage.
