OK----That was fine, but just a warm-up. Now let's see if we can separate the "men from the boys".
I don't know what this plane is---the mystery has gone unsolved for a long time

. I have had ZERO luck with the guys from SPA---several guesses I know are incorrect, and no winners[

]. Can anyone tell me what this plane is, and who the pilot might be.

All I know is this is a mid-60s vintage picture, and was taken at a Detroit Invitational.
