Airfix are pretty good, Phil,but because of the kit, webbing, etc, military figures are simpler. Personally I prefer figures which are just visible in glimpses in the more closed cabs of close-coupled pacifics. I like the blue-grey to be fairly pale and washed out, just to be seen as *there*.
Commercially, once upon a time I'd have got out the green-putty (used by miniature sculptors for masters) but, my usual winge - bloody health!

PS: BTW Mr Tetleys, my coach-related response to you appears brusque in hind sight - and anonymous, too. Didn't mean it to be. Lack of sleep, probably. Sorry. ;-)
