John, I'm not sure if you have seen it or not, but here is a video slide show of C&P Aviation's P-82, located here in Minnesota, which is under advanced restoration at this time, with the goal of having it flying by 2013. There is also another P-82 (an XP-82), under restoration to fly by 2013 as well, in Florida, however it is not nearly as far along yet at this stage, though they are making amazing progress as well.
These photos were taken shortly after the center section was finally mated with the two fuselages for the first time since restoration began.

The only stumbling block that was in the way of both P-82's from completing restoration, was resolved late last year, with a well-known prop manufacturer, I believe in Germany, agreeing to reproduce the rare/extinct propeller blades for them. The reason for this is because on the P-82 they had a left-hand set and a right-hand set, and blades for the unconventional set simply cannot be found.
In 2013, both P-82 groups plan on getting their Twin-Mustangs to Oshkosh that summer, C&P's P-82 running Allisons, as originally, and the XP-82 running Merlins, as originally.
