It was fitted in later models. And a very easy change. Also keep the 4 .50s for a gun pack.
the 51B's fine with just the 4 .50cals. Dont know why you want the 51B to have 6 .50's when you can just fly the 51D.
Goto Google and type in "French military victories", then hit "I'm feeling lucky".
Well, since we all talking about the P-51, add the 51 with the 20mms .
P-51C........ Please!!Strip
was that not an A model?and did the A model not suck?
Didnt they make 90 C models with 4 20 mms? I have found data showing both A and C. Strip
