P-51C-10 & C-11-NT

[drgondog]

Phil - as you know the dorsal fin was first added in the P-51D-10 series when the USAAF and NAA believed the elimination of the Turtleback from the B/C to create the teardrop canopy somehow contributed to the yaw issues in a high speed dive in the new P-51D-5.

The question of 'all for PTO' could only be truly settled by the movement records. Having said that, the ETO started retrofitting the P-51B/C's (and all P-51D-5's) with dorsal fin field kits in the October to November, 1944 timeframe.

Having said this, if the only real change to create the -11 was addition of Dorsal Fin, then said field mod probably should have resulted in re-identifying all -10s as -11's ???

This is about the time that the metal elevator kits were also installed on all Mustangs.
