"High US content" pretty much says "Not really emtirely made here in the US", dunnit?
As I'd heard, the guts were being put together in the US with the machinery (and more importantly at least as GTs business angle was concerned) and coatings bought from the Ownesboro plant. I thought the assembled guts were then shopped to China for final assembly.
Wonder how these guys are makin' out...
