Hello Guy,
For the night fighting Biffs I am still not too sure of the colour schemes as the overall night schemes are variously portrayed as grey, PC10, mid blue or NIVO with little in the way of consensus. If I've missed developments in this area, I'd be delighted to be updated!
For the post-war selection, I'm not sure just how much demand there would be. WNW have covered most of the "interesting" versions with the additional radiators and other gubbins for the middle/far East, so those I was planning were mostly for home-based units. When I get the post-war Ninacks out (now we have a printing solution on the horizon, that will be in a few weeks, I hope), I'll be in a better position to judge the popularity of any post-war Bristols.
