Just thought of another guy you might want to look at - Rob Ijbema.
Dutch guy lives in the UK, known him for 20 years. He made models for most F3000/F3/FF teams back in the 80s. He mainly does paintings now rather than modelmaking but has links to models on his site.

Last time I saw him was at the Goodwood Revival 2 years ago. His young son had won the design-a-car competition at the Festival of Speed. His prize was to have his design built, at the Revival by Lord March's engineers and Stirling Moss drove the lad around in it before the crowds!
