The MiG is actually a 17 vs a 15. I always get a kick out of that B-47 they have parked out back. I think there is an F4-C on display outside now as well.
The BF-109 and P-51 are actually fiberglass replicas. If they still have the ME-163, that is original, on loan from the Smithsonian.
Me, Willis and Tate used to stop there on the way back from King Orange. For a long time, all the docents there seemed to not only be AAF veterans of WWII but it seemed like every one had survived a shoot down over Germany! They had some harrowing tales to tell. Its a great little museum to visit.
