Thats the 69 single vacuum advance

I am pretty sure we will find the new 1970 distributors had the dual vacuum advance.

Mine did as did a few others that I have seen. Pete, this grabber green was a really original car when bought by a GM engineer around 1983. Check out the advance. He has since sold the car after almost 40 years of ownership.

Gary, any markings on the single advance?

Bob couldn't find any on his. They could be in a place that you cannot see when mounted though.Pete mentioned that the pic is indeed of a 69 advance. I got a few dist in my attic with single advances but i'm not sure if they are 69s.  I'm used to looking for "HP6" advances. I think you know what I'm talking about
