My trusty hot-wire cutter comes through with the goods again.I've opted to paint the block-houses in GW "Boltgun Metal" washed over with some burned sienna as a light tarnish and to add some definition on the corrugations.
I decided on this approach as there was no information really on whether the blockhouses had been painted or no. Besides, I squinted at some poor quality, black-and-white internet images for long enough to convince myself they were bare metal!
