I started a 2nd profile for a new aircraft, only to discover these two are the same aircraft only the 2nd is a total rebuild! The FAA even has a separate type and s/n for the plane, so it becomes two different planes in a sense. Here is what Warbird Information exchange has to say about it:
TP-40N 42-104721 (N293FR) - reported having been test flown at Chino. This is an evolution/rebuild/rebranding of the same aircraft that originally was at Evergreen, which was based on the wreck of P-40K 42-9749, recovered from Alaska where it had originally served in the Aleutians, and originally restored as a P-40K. Now the airframe has been rebuilt as a factory-built TP-40N with the serial number 42-104721 newly assigned, an identity from a wrecked (and) parceled-out P-40N that was recovered from New Guinea where it had originally served with the RAAF as A29-499.
The new identity was established 11/13/18.
