How it is derived

A constructor id whose earliest race_entries row, by races.date_iso, is in a race it won. Alfa Romeo: 1950 British Grand Prix; Mercedes: 1954 French Grand Prix; Walter Wolf Racing: 1977 Argentine Grand Prix; Brawn GP: 2009 Australian Grand Prix. The 1950 British Grand Prix was the championship's first race, at which every constructor debuted. 377 entries carry no constructor id, most of them Indianapolis 500 cars, and cannot count.
