I think the "family culture" still existed in the trenches airsupport, but I agree with you corporately.
Best example of TNT/NC thinking I can think of was the pooling of parts between TN & AN. This was one of the first things stopped IIRC, and the first thing to bite them on the arse when we needed a spare!
Yes, not just spares either, same with manpower.
In the good old days at minor ports often used to be a case where if you got your aircraft out okay and the other mob was delayed you used to go help them, NOT post TNT/NC.
