My gosh, that's nice, Henry. After I pointed to that picture, I realised that there are two styles of that wheel, one fitted to Ford GT40s, the other to Shelby Cobras. Although Rudl's is identified as GT40, it's a Cobra style, the difference being the webs to the hub centre. You've done the GT40 one, which is more involved than the Cobra's, the similarity is superficial. And when I Google-image-searched Halibrands, the image that Rudl posted came up as somebody's Solidworks effort. Yours is gorgeous. Kudos.
