I've very much enjoyed this thread. Excellent modelling and interesting info. Like many, I suspect, there is one of these new Hurricanes waiting on my shelf for a future day - my modelling is very slow at the moment.
I found the discussion on exhaust staining very instructive and it raised the question of how staining would have been on the Battle of Britain Hurricanes? It was summer (warm) and often they'd be climbing at full boost to get to altitude so how would that affect the stain? That would be on a rich mixture, wouldn't it? Black with a greyer edge perhaps (no doubt they ran much leaner on return from combat to preserve fuel)? Or would the staining be more grey as the richer stain could get stripped away during leaner mix conditions. What do you knowledgeable modellers think?
Sorry, messed up the quoting system there. Will get used to it ASAP hopefully
