The clock in this photo is an Ingersol, the face looks like a BMW speedo, the VDO 8 day clock now on the bike was found a couple years later. I found this pocket watch and holder in England. The bell is German, and was found at the Ulm Veterama. The Hagus mirror is also visible on the left crashbar. (my ISDT photos show it there) You guys have more and better photos than I do. I am somewhat computer challanged, but can still find my way in the garage.
Yesterday, a German guy sent me a dozen photos of the Herbert Schek 750cc ISDT bike from about 1973, great detail and I am going to copy some of his ideas.
