I remember flagging at Shell In at a VSCC meeting at Oulton Park - probably one of the handicap races - gave a blue to a 4.5 ltr blown Bentley as he was about the be mightily harassed by the full race Morgan 3 wheeler - trouble was he could not see the Morgan as it was below the sight line of his mirrors - somehow they both managed to get round the corner OK and the Morgan passed the Bentley round the outside of the banking, so at least for a fleeting moment both drivers where at about the same level.
Being VSCC drivers I did get a thank-you wave from both of them on the slowing down lap.
