I was watching some of the other videos of the Brothers collection and most of the information the commentator gave was good, but some was pretty off the wall. Like the FT6 AAR cuda video where he says AARs weighed 3000 pounds. And the TX9 T/A where he said the steel wheels were unique to Challenger T/As. The only thing I saw unique about the steel wheels on that T/A was that the trim rings were missing. And someone with sharper eyes than me will probably tell me they weren't real '450s?
