tempted to do this project in 6mm if I can find suitable proxies, as I think it’ll give a better impression of the scale of  some of the actions (and allow me to field trains and other stuff)...

I’m thinking of using Great War British or Russians for most of the Federals, some pith-helmet artillery from the colonial range and Boers for most of the revolutionaries, but all other suggestions/recommendations very welcome

I don’t think the Mexicans are likely to appear in the Pony Wars Range, are they? Go on, Pete, it’s ‘only’ one or two more packs...
