MDCAV,
I've not relied on photos,they are invariably misleading. I acquired the original steeringwheel with 1/4 inch thick plastic emblem on boss, together with overflowing lever arch files of original letters from FAV and Gulf Racing, plus original photos etc.
How the wheel came to be parted from the second prototype car is detailed in Roy Salvadori's book/letters. He also mentions how the leather rim came to have a small depression in it. I'm sure there were variations, the black one springs to mind. However having collected original parts for nigh on ten years, i'm happy with what i have.
I do have plans to reproduce the emblem, but its very time consuming, remanufacturing original parts and at present, i can't justify tooling costs, from the interest shown by others.
