I have asked Andy and according to his website , and I quote " A few had the 99cc Triumph Tina T10 auto unit and larger 8'' rear wheel " . End of quote. Can anyone prove otherwise? I have also heard that another of this type has recently surfaced in Canada. I am particularly keen to get to the truth, could it be that these ones were factory built prototypes for the foriegn market and are 'right' so to speak ?
