Virgil Exner's XNR on Leno

I guess I'm a bit confused. Is Leno's piece about the original one or the copy some car show remade? If yellowdart69 is correct about it being the original one and stored at RM Restoration I want to go see it too!
@bcschief- Al Mulla sounds about right for that part of the world, though I'd have guessed Lotta Mulla!
