I’ve been told the parts are displayed at the “Militärhistorisches Museum” in Dresden/Germany. The display board says “Wing of a North American P-51D Mustang Fighter, USA, ca. 1944” and “the wing of this P-51D was recovered in 1969 from the “Schweriner See” (the lake near Schwerin/Northern Germany).
That will be the place I was referring to.
