My Dad, David Drisin was the owner of #555 for a very short time. her name was "Orion" and he raced her in the Benihana Pt Pleasant Race around 1971. He also had a Magnum 27 saloon that he raced the year before when he won the production class. I remember him saying that the Bertram was not safe at speed as she danced dangerously and couldn't be controlled properly. I think he sold after only a year. i don't know for sure if she then became "Rio" by the new owner's painting over the first "O" and the last "n" in ORION. But that ia my assumption.
