The picture is of an airplane also called the polecat in name only. It is a completely different in design to the Pole Cat that we know from the formula one days. Bob is right that this one is a Ricky Rat (or what we know as a ricky rat) named polecat. However, my QM design was from a modified cassutt by Erine Prosch and it's correct name is PR-2 (source is R.S. Hirsch). But more commonly known as the polecat. Prosch also did the Loki, and I believe the Loki was the first version and the PR-2 (polecat) was the second.

Prosch's polecat appeared in 1977, therefore I think his is the real polecat since the one pictured above appeared in 1980.
