Hi Trevor...nice to see our rain has spread! It's finally stopped here.
Well the Freedom 180 is described as a 4 seater but the picture certainly looks very much like Graemes?
Found a photo of the Freedom 28 and it appears not to have the visible engine exhaust, and more importantly was around and flying in 1986 when it one a prize at Oshkosh! Graeme had said it was from the mid 90's.
