Closing the loop on this thread, because I can leave no question unanswered. There were 31 cars flight judged:

3 solid axles

13 mid-years

7 sharks

6 C4s

2 C5s

There were also 10 performance verifications (2 solid axles, 4 mid-years, 2 sharks, and 2 C4s).

Plus the usually ancillary display cars, etc.—probably about 45 cars on the show floor.
