They've been undercoated with Halford's grey primer and then dry-brushed with white in this picture. Next, I used a cheap Americana (read folk art) yellow ochre to provide the basic imperial khaki base colour...

Other recent acquisitions have been some transports for the redemptionist forces in the form of republic gunships:
They're 1:172, which is more 10mm than 15mm, but I think they will work. A snip @ £4.99 from The Works (a UK based retailer that sells off bankrupt stock). More on those later.
I'm still looking for the right decals for my other vehicles, but I'll update you all when they get sorted.
It's Sheffield Triples in a couple of weeks, so I'm hoping to find something suitable there.
