I've looked at a lot of continental pictures, old brochures and manuals over the last week. I did just look at first 20 pages in the Rupp gallery and ran across the image just posted too. It is very similar to mine, except the chain to the rear wheel sprocket on mine attaches to a sprocket on a jack shaft. This shaft sits just forward of the swing arm pivot point. I've see pictures of Customs that used this jack shaft. I will post pictures tomorrow.
