He made a few (under 5) sets of Stainless steel radiator shrouds to replace the chrome ones on most R3s - reduced size with squared edges from memory. Look at photos of Steve's R3 or Hogweed's.
There are a whole lot of different at least 6 I have seen RADIATOR GRILL STAINLESS SHIELDS LIKE FLIPMEISTERS. I HAVE FLIPS AND HIS CUSTOMER SERVICE IS GREAT AND PRICE THE LOWEST - Sorry bloody caps key. Bull dogs, full image or just face are common as are UK flag versions, an EU flag, and quite a few more, with model name like 'Classic', 'Roadster', 'Touring' etc.
