Hi Carawagon,

the film is listed:
http://imcdb.org/movie_59986-Die-Gentlemen-bitten-zur-Kasse.html
but has no FC in it.

Three more films show FCs (plus 4 101 FC):
http://imcdb.org/vehicle_105568-Land-Rover-109---Series-IIa-FC-1962.html
http://imcdb.org/vehicle_138935-Land-Rover-109---Series-IIa-FC-1962.html
http://imcdb.org/vehicle_86567-Land-Rover-110---Series-IIb-FC-1966.html
All three are listed as 'background vehicle', which means they will be on the screen for just a few seconds or less.

I will soon add some Land-Rover documentaries that should hopefully show more FCs.
