Thanks all for advises, I appreciate each one to try.
Jay, thanks for your important reminder. Indeed, the mentioned Baby Doll gave me the idea for the Dunlops but meanwhile I forgot about this very car. BTW it is Stefan's car. It is often associated with Günter because Günter posted the pics from Stefan's Baby Doll. Certainly I will ask Stefan about his source of Dunlop styles.
www.talkmorgan.com/ubbthreads.php/galleries/111039/1The late and very alive Lew Spencer helped Stefan to detail her, Richard Thorne helped to realize the project and after all that happened succesfully, MMC could campaign the story as a companies project. At the earlier stage when designing her as a one off, Stefan decided for the Dunlops to get historically matching wheels but no spokes.
BTW Günter's Baby Doll is Westminster Green and has Morgan standard alloys, which I must admitt give his car a very good look, but the Morgan standard alloys are available only with one defined offset. My dealer changed one hub in last winter to try standard alloys but my car is too wide for them, and the Dunlops will be made with different offset and size.
