Do you have a picture of the newspaper page that came from?
Well even if you do, I suppose Michael might point out that if you have an old newpaper printing press from the 1960s lying around in your garage with some blank vintage newspaper paper, you could easily forge the article.
Well I suppose there is still the possibility that Paul Cunningham purchased the car from the Abidin family on or prior to August 1963. But then again if Ann got the 1964 registration application, that makes it unlikely that Paul Cunningham owned the car, unless, and this seems unlikely, for some reason, Ann bought the wreck back after the mechanics lien against Paul Cunningham came through. It does seem more likely that Ann owned the car, Paul got to drive it and keep it at his home, but the Abidin family finally came back to collect the wreck that they owned before the mechanics lien came through.
