Very good points - not sure how I forgot about that Ueno car. Wish we could see more of it sometime too.
If that brown one that was spotted in Mexico is really #039 it may be original too, though I would hope McLaren had nothing to do with the wheels.
Hopefully the Brunei collection is still original - I do of course wonder what sort of condition that might actually be in those cases.
