Over the years (and there has been quite a few) I've seen a ton of Dominion 42's . Lots and lots of the light greens but very few of the dark shade. This particular insulator is a nice shade of green and in excellent shape. A CD 154 skirt embossed DOMINION - 42 and on the back side the D enclosed in a diamond over a small 3. Asking $40.00 plus actual shipping cost. PayPal (friend mode) or check.
