I can't begin to imagine the damage you could do to this list with Spitfires, Tom! I guess the less 'well-known' Mks would be a real boost to the group. I hadn't thought about it but I might publish a small wish list some time in late August if we are going well!
That said, and speaking of 'Supermarine', I'd like to put out a general call for an S5 or S6a that raced for the '27 or '29 Schneider Trophy, which would really fit the bill and fill a gap historically!
