I can help on the Texans. A little fuzzy, but this is close. The Texan A-6's (from Academy?) are probably postwar, as they were a step between elementary trainers (Moths,etc) and high performance fighters, including the danger factor. The best kit is the Hard II from Airfix. However, you fellas used thousands as the SNJ in the Navy and elsewhere.
The only problem on the A-6 that I am researching is the number of metal ribs on the canopy and a very distinctive exhaust runiing from the engine to the leading edge of the starboard wing. For the British Commonwealth Training Plan this is a must. Also bewar of A-6's with an electronics dome of some kind between the canopy and the tail.
There are still 15,000 flying.
