The company that brought us the P-51, North American, made the P-64 as an export fighter. Many think of this as the export fighter version AT-6 Texan. Since North American made them both, it’s easy to understand why with the similarity in the airframes. The history of this plane is somewhat cloudy with 7 reported sold to Peru and a flight headed for Siam but never making it there. Six were delivered to the USAAF but never saw service.
This particular P-64 was once a Harvard Mk IV. It was modified to be a P-64 which isn’t a long stretch since the Harvard is a T-6 and the P-64 was designed from the T-6 airframe. Since there is only one known original P-64 in the EAA museum in Oshkosh, it’s pretty cool to see this one at the Wings over Gillespie airshow because otherwise, we wouldn’t see one flying.
