Hi Kurtl, if you would check the report attached (right at the bottom)
https://www.cwgc.org/find-war-dead/c...gid=null&pid=2
you will see the full number, looks like there is a typo in CWGC DB.
As for aerodromes - Chrudim + Nemecky Brod were both on territory of former Czechoslovakia (Böhmen und Mähren during WWII), now Czech Republic. Nemecky Brod has been re-named to Havlickuv Brod in 1945.
