Oh sorry didn't realise you had to be a member to see it. (It's not mine btw).
This is a genuine piece of Fernando Alonso's 2004 Renault F1 car, this actual part was on his car when he had the famous incident with Ralf Schumacher in the tunnel at Monaco.
The dents etc are from his helmet hitting this surround and doing its job.
"I would reccommend collection, or we could meet part way, i think postage would not be an option as i feel this quality item will get even more unwanted and un-authentic damage
Bargain at £300 or may consider offers"
