Soulyss, you are correct. Our 51B has the same Packard Merlin V1650 as the 51D. The malcom was added for better visablity vs the birdcage, and to my knowledge malcoms were not factory added option. So that makes the B the only field modded aircraft in AH.
P51B in game uses the Rolls Royce Merlin 61 (same as the Packard Merlin V-1650-3 ) while the P51D uses the 66 (which is the Packard Merlin V-1650-7). I can find information that the V-1650-7 was 1,490 HP/1,720 HP but no information on the P51B's V-1650-3's HP.
I also believe that the P51D was slightly lighter an airframe to make up for the extra 2 .50 cals correct?
Malcolm hood is a newer addition to the P51B in game. it used to have the birdcage. never knew why they replaced it with the Malcolm? most likely for the better view.
Backing up statements that the Mustang MK III is the P51B/C and the Mustang MK IV is the P51D/K. Dolby, like they said, the only Allison Mustangs were the A model/MK II ones. A nice plane but no where near what the mustangs in game are like
