For those interested in the history of this particular chassis (RA107-05), I have just learned a few more facts of its whereabouts.
The initial shake down was done by James Rossiter 28th April 2007 in Barcelona.
Rubens, Jenson and Christian Klien drove the car for the following test in Barcelona 30th April - 3rd May 2007.
The car then went back to the factory in Brackley for a full scale wind tunnel test, prior to its race debut at the Canadian GP in Montreal.
After the end of the 2007 race season, the car went on loan to Super Aguri and went for winter testing in Barcelona 13-15 November, and Jerez 4-7 December 2007 and was driven by Ant Davidson, James Rossiter and Takuma Sato.
RA107-05 then became Ant Davidsons race chassis for the 2008 season. He raced the car at Melbourne, Sepang, Bahrain and Barcelona. After Super Aguri's demise in May 2008, the car was returned to Honda where it received the 2008 Honda Earthdreams livery that its currently in.
The car was then finally decommissioned in the beginning of 2009 and sold to a Brawn employee who intended to take the car to shows with a rFactor simulator installed. This apparantly never happened, and the car was sold to us in December 2010.
It was news to me that that the was was AD's race chassis in 2008, where it raced with #19 on its nose, alongside Takuma Sato's #18. RA107-05 therefore has clocked up 13073 racing kms, rather than the 8000 kms or so I previously thought it had done.
I found this photo of RA107-05 as it looked in Australia 2008:
