One more thing. I discovered in my research the likely reason why some of the early competition cars had Bell-style sprint car steering wheels instead of the original wood-rimmed wheel. It turns out that the early cars had a worm-gear steering box, and that it wasn't unknown for the steering wheel spokes to break under heavy track use! Naturally, it would be prudent to upgrade to something stronger. After the cars switched to rack-and-pinion steering, that problem went away. Since all the FIA-style cars I've seen have the classic wood-rimmed wheel, I guess that is what I'll use, in order to be "correct", although I really like the look of the Bell wheel better.
