I do have the Tamiya (50898) body kit which comes already black. It has the full sticker kit to match the McLaren/West team. It doesn't say "West" though, rather it says "Best" to match the scheme for countries where Tobacco advertising isn't legal. Not only that, I'm sure Tamiya doesn't want to pay for any extra licensing to "West".

I'm assuming you knew all that, just wanted to clarify just in case.

Worth noting, I do have some decal sets on the way that exactly match the BAR Honda (Lucky Strike) and Ferrari (Marlboro)...including the tobacco logos! They are supposed to be made to fit the new F201 body, but I'm thinking they will probably work OK with most clear F-1 high-nose bodies.
