Thanks Paul. That helps quite a bit. I looked at a pair at a swap meet in Bowling Green, Ky. My buddy, thankfully, pointed out that they were different. Apparently one was 1st, other 2nd. I know of another set in my area. They appear to be 1st design by pics. thanks for the education. I never paid much attention and I never do on parts, until i am in the purchase mood. You brought me up to curve.
