Lots of Left Wing journalists from Hampstead who've gone to Spain and joined the Militia?
Hey, honestly, I'm planning on using a few of these guys (the three in the centre, actually) for militia in Russia. They'll look really out of place there! But I figure, urban dwellers look like urban dwellers in another country in the 20th century. There's a few that stand out - there's a guy with a dark beret/flat-cap and beige coat (which definitely says 1930s to me); if they were the other way round I think you (or rather, I) could get away with saying he was 1920s. The chap at the back looks like a Chicago gangster, but with a brown suit, tan hat with brown band, white shirt and black tie wouldn't look out of place I don't think. Though you have to question any guerilla who thinks a tie is appropriate.
