RSR Engineering - are they still going?

[infernored]

Was wondering if anybody knew if the above company were still trading as Porsche specialists as they did some work (including servicing) on my 930 in 1999 before I bought it. I am trying to get replacement stamps for my service history as the original book was lost by previous owner although I have every bill and paper record ever produced for the car to prove its history and mileage. They certainly don't seem to have a website so I am not sure if they are still trading, I have found an address for them in Weybridge Surrey but the info is old.....
any help on this one would be gratefully received
