That's right, No. 9 and that's why Wynn was so careful to clearly define his parameters following his research.

It applies to aircraft, too. For many years, the Hurricane in the BofB Hall at the RAF Museum was classified as being 'of the period' but not having taken part in the battle.

Then, just a few years ago, an amateur researcher found the serial number in a veteran's logbook. The RAF Museum researched further and concluded that 'their' Hurricane had indeed flown just one sortie in the BofB period and so it is, indeed, an actual BofB veteran.
