Me too. So, spider murphy, did Harold Boardman Jr; (you forgot the Jr.) run a business named Boardman Motors in Augusta, or did you made that up?
My source says he rebuilt the car with a few friends, which should make it purely a one-off. Then call it Custom Sporster or 2-door convertible, that doesn't make any difference since it's not a production model.
EDIT: I wrote this before seeing Paul Jaray answer, so it was a reply to Joao's post. Now, Paul has the same source than spider murphy, and I had the same as Joao. But both spider and Paul are more correct. The proof is that 119 inches was indeeed the wheelbase of the Commander (Champions rode on a 112 inches wheelbase). That settles it.
