Fox> Okay, hold onto your hat!
First, here's a link to the articles on the restoration of the P-47, serial number 42-27609.

Now here's a link to "Pacific Wrecks", which contains some data on 42-27609 and where it was recovered - Dobodura (which contained several airfields).

You may click on that small image in the upper left to get a larger picture. That made me go "Ohhh!"
Now, this link shows some earlier images of 42-27609 (maybe) taken in 1972. It looks more intact in these photos than what you reported, so I wonder about that.

And this about it's recovery.

This article seems to suggest that the aircraft belonged to the 58th FG, but the restorers seem to think that it was instead with the 35th FG. The article also gives a place and date when it was abandoned.
"From there, the trail goes cold until 42-27609 was written off at Dobodura, Girau Airfield, Papua New Guinea on September 18th, 1944."
Also, this article lists crashes and pilots for P-47s in the Pacific, but nothing that I can find flown by a Joe Potts.

Lot of stuff to go through, and the condition of the wreck shown in the older photos belies the condition it is shown in in someone's yard in New Guinea.
Still, it might be worthwhile to contact Joe's son about this, and try to ascertain if there is any record in his papers about when he crashed, or contact the people restoring the aircraft to find out if they have any further information on the plane and the condition it was found in. Perhaps someone may know more about the aircraft Joe was flying when he crashed, and it may already be a known quantity. But it is interesting, since no one seems to know why 42-27609 was written off, or who might have been flying.
Meanwhile, there's an interesting image that I had not seen of P-47s in flight, and they seem to correspond to the image I earlier linked of Hunter's P-47. So the order not to decorate the Thunderbolts didn't hold for long!

PS> I do note that there are other candidates for Joe's plane, such as this one that apparently ran out of fuel and crashed.

Also, after some digging, it's possible that 42-27609 is being confused with 42-27608.
