The measurements are 73cm wide x 32cm chord. So that's why I think it's a 2009 spec wing, i.e the 2009 regs specified a maximum 75cm rear wing.
The Brawn rear wing was completely different to this wing. Honda did a test day with a 2009 front wing on their 2008 car, with Bruno Senna and Lucas DiGrassi doing the driving, but the rear wing in the photos isn't the one I have here. I think the wing was run on a car because it has plenty of stone chips.
Anyway here are the photos:
