I’m not sure but I think this Cat carried the grey colours, shown above in my photos, from the day it arrived in The Netherlands or shortly after. There was an orange Cat in the Netherlands in the late eighties and/or early nineties (now in a museum in Norway) but I can’t tell you if that one ever flew a display at Duxford. If you know an approximate year, you could search through the scramble showreports for Duxford here: http://www.scramble.nl/showreports

Edit: I took the photo below in 1991. This one was flying as C-FIZO at the time, see here for more about this airframe: http://www.warbirdregistry.org/pbyregistry/pby-46645.html
