Actually, I am tending to believe that 43-12452 was possibly the first Merlin engine Mustang captured by the Luftwaffe. From your book "Angels,Bulldogs and dragons":
Engine blew...made a wheels down dead stick landing on a German airfield."
Since this took place on March 29,1944, it would have to qualify. Obviously, it was not flight ready by the time that 43-24825 landed on D-Day.

Re-engined by the Luftwaffe at some time, it was made flyable by ZIrkus Rosarius only to be abandoned at Goslar A/F.
