This aircraft originally served with the Condor Legion, and was returned to Germany in the 1950s.  As can be seen, the aircraft currently carries fictitious markings of the Geschwaderkommodore of JG51, and as is common with other Deutsches Museum exhibits, various sections of the airframe have been cut away to show the underlying structure. 

The following three photos were submitted by Steven "Modeldad" Eisenman:

These five photos were submitted by a very helpful Lair visitor whose name escapes me; if these are yours, PLEASE let me know so I may properly acknowledge you!  :)  Incidentally, the last pic is very interesting- that's a Bf 108 immediately behind, note the tail structure similarities...

UPDATE- The photos were submitted by Hans Trauner of Nürnberg, Germany, who sent a quick note to remind me... Thank you very much, Hans, these are greatly appreciated!
