Still can't see anything, but if you go to
you get something but I doubt its a restorers label but anti theft going by the contact number.

Rowe points out that this is not a substitute for making a full provenance check on a vehicle that you are thinking of buying: “A check with the ISR is fast and immediate. Crucially, you can make a call to 07000 111333 at any time of the day or night, and speak to a real person who can reassure or alert you to potential problems. This includes whether the seller is recorded as the owner on the ISR, whether the vehicle has been reported stolen or if the registration mark matches the chassis number and other details. The police regularly call the ISR to check suspicious vehicles.”
