Thanks Rolly,
I was able to dig up a 1966 write up. The write up describes 4 variations of the 6850 selector. They are CA, CK, BV & BJ. It goes into detail describing each of their differences. I will try to read it this weekend. But, the wife is away! I can't comit to it though. I am planning on doing some house projects & cracking the seal on a bottle of whiskey. Wish me luck.
