What Aircraft is This?

A forum member has PM’d me with an interesting aircraft I cannot identify since that is not my forte.

Looking on http://www.militaryphotos.net/forums/showthread.php?216499-Any-Idea-what-aircraft-she-is (cheating a bit) it appears to be the only Piper PT1 built

The Piper PT-1 was a 1940s American two-seat primary training monoplane designed and built by Piper Aircraft at Lock Haven. A low-wing tandem two-seat monoplane, the PT-1 was the first Piper aircraft to have a low-wing. It had a fabric covering over an all-metal fuselage frame and wooden spar wings and tail unit. The PT-1 had a retractable tailwheel landing gear and was powered by a 130hp Franklin 6AC-2980D engine
