Davedove:
by viable colours, I mean colours that might have been plausible around the time of the '45. If all those colours existed at the time, well, then I have a bit of a debate then don't I? I am leaning towards either Hunting Stewart, Ulster Red, or Brown Watch.... and perhaps the Buchanan Muted. They all look good, and all but the Ulster have solid earth tones in them. But I have read on Matt's site that the Ulster is a pretty old pattern...so that is a definite contender.
