Ed in your link look at the Speedtwin that is the 5th bike down. The junk on Craigslist has that same primary cover best I can tell. It also has an alloy head. That narrows it down pretty well I think. That primary cover has the small tear drop front not the larger front that housed the alternator in the early 60s models. The early 50s and earlier mostly had an iron head. I could be wrong since those pictures are very hard to get any detail out of but that was how I came to my conclusion. The bikes I am talking about also had a magnito, generator in front of the jugs and a magnito behind the jugs.
