Hi Stig,
yes, this is interesting topic, same like Hawker Hurricanes during same period (start WWII to Battle of Britain).
Plane K9867 ZP-J was lost 23.5.1940 - S/Ldr. F.L.White forced-landed at Calais-Marck. During few hours was rescued by pilots of 54. Sq with Miles Magister covered by 2 pilots.
http://www.bbm.org.uk/airmen/as-leathart.htm - there is wrong date

In this link and info about S/Ldr. White, there is photo of pilots 74.Sq - some of them was shot-down during Dynamo operation and some of later.

From my view, in the excellent book Battle of France Then and Now, there is just the typo - wrongly K99
77 and right one is K99
57
But - maybe I´m wrong :-) I´m just amateur in this part of history :-)
