Michael,
he could be a person like the guy I ran into at a show in Pittsburgh. there was a tiger parked on one side of my fastback and an alpine 5 on the other side. he came up to the car and asked why someone put a sunbeam engine in the car. he went on to explain to me that a tiger was a ford powered sunbeam and the alpine was the 4 cylinder version. my 69 GT was not a sunbeam. he did not know squat about sunbeams. my point is that this guy may only know what someone has told him about the hard top and doesn't care or doesn't have the time to research all the details. maybe he had never seen a sunbeam until he found this one. he has something that he thinks is worth some money and hopes to sell it. it happens all the time. i'm sure someone with interest in buying it will do their home work.
