I had some luck at the Navy Historical site at the following link searching on NATC or Patuxent River. Nice profile of a NATC F6F attached/ Aviation (navy.mil)
I spoke to Chad Miller who has a role at the Museum. He’s getting me a POC at the Museum re: photos.
Thank you very much. Re: the Pax Museum, I spoke with the Collections/Exhibits folks today and will be meeting with them tomorrow (Fri 31 Mar) over at the museum to have a look at what they have, and to also get close to the aircraft for photos and possibly measurements of some of the markings.
