Jaguar Racing Cap Identification

Hello to all the Jaguar sleuths out there.
A friend of mine who worked for Ford Australia kindly gave me this cap with a story of it’s history.
However, before I pass on the info given to me can anyone identify the signature on the brim please.
it’s said to be circa 1998/9

First word looks a bit like Mark, could it be Mark Weber? But he wasn’t with Jaguar until 2003, so timing a bit off…?

Thanks…my thoughts exactly…but you’re right about Mark Webber not fitting the timeline.
