Both insulators are VVVNM. The pony on the left has a strong vertical bar on the front, and the bar on the back side is much weaker. My asking price is $30.00 + the actual shipping cost.

The Pony on the right has a B.T. Co. of CAN. marking on the front along with a large diamond, and a blotted-out marking. The back has a large diamond. There are a couple of very very hard-to-see small ticks that I only mention for accuracy. My asking price is $35.00 + the actual shipping cost. Buy the pair for $60.00 plus the actual shipping cost.
