Well... in his defence, they made T-6 Texans for a looooong time and we used them as primary trainers for about as long. Perhaps they refer to it as their Korean-era T-6 (a notable distinction, meaning its one of the later models, or maybe even RARER one of the few US T-6s to see COMBAT during the Korean war as a forward air controller), or maybe that it was used by the S. Koreans for their purposes and eventually made its way back to this side of the pacific.
While it's probable he's wrong, if not then their T-6 is much cooler than your average/common Texan (a serial/tail # might help).
