P-51's in movie "Empire of the Sun"

Jim Doyle twisted the electrons to say:

In the film Memphis Belle, they had a Bf109 with a Merlin engine (same
engine as in the spitfire and the P51), so they could have a mostly
genuine enemy plane (well apart from the engine).
Of course there werent any originally engined 109's available.
Just the one actually, 'Black 6' at Duxford - (has since crashed into a
field at the hands of the then CinC Strike!)

IIRC, aren't there effectively 3 "types" of 109 around?

[1] Genuine 109s - non flying since 'Black 6' got bent. :-(
[2] 'Mules' that have been fitted with a Daimler-Benz DB-605.
[3] 'Mules' using an engine other than the DB-605.
