Yep, car looks familiar, IIRC the "Zerex Special"?
The most prominent and the only one I remember, called by that name, was the Penske "Zerex Special", raced in '62, as a rebodied 2.7L Cooper F1 car, with a tiny seat, outside the frame rails and outlawed for the next year. He widen the frame rail for '63.
That said, there could have been one I missed but, I thought I'd post this one, because it was a very interesting car for it's time.
My picture of it, at the '62, Times Gran Prix and a picture of him sitting in it and and a better one, from that same magazine.
