Two aircraft, properly done of course, would be 'no-brainers' for Corgi. The first is a
Phantom of the Ruhr Lancaster and second the
Friday the 13th Halifax

.
For the POTR Lancaster I think they could release 1500, divided up (500 each) into three distinct liveries/markings, namely the two wartime squadrons (early and late) and the current 'combined' markings of the flying BBMF version
