Nope I have liked it for a long time.
I bumped into the info accidental looking for the Bomb Guide stripes in another thread.
I love you guys that know how I think.
And what would be wrong with a cannon armed P-51?
You just happened to get fixated on a very rare version of the P-51 that had four cannons? Yeah right.
You were so fixated on it that you just now started finding good photos of it, per your own statement in this thread. You had to go search the web for data on its service, and even then what you posted doesn't identify the aircraft used for those sorties.
Basically, your posts in this thread all come across as somebody who wants the four cannon P-51 and is now trying to justify it rather than somebody who was interested in it, knew why it should be added and came here to post about it.
