Good luck; I brought up the possibility of a 25 year rule when this vintage pattern thing was heating and I got somewhat trounced over it. There is the BPA and then there is the SPA, and that is how the consensus decided to cope with the questions such as yours. My perspective is that during the season in which these ships would fly, one might be flying a DB against a Tipo in the same class. Don't remember why the year 1975 was drawn, but I'm sure someone will jump on this one. Here we go.
