Quick question.
Have any of you folks ever seen a large terrain piece done up as power station or factory, with a large, finished, accessible interior based around an old hobby steam engine, like the Wilesco D20?
Because it seems like it would be a magnificent piece of terrain. I don't think I could bring myself to destroy a nice, new working model, but perhaps one with old tired seals or defunct pistons? Something that didn't cause significant visible damage, but had rendered the engine inoperable.
You'd have to do something about the raised floor (perhaps a little too high for gaming, but you'd have to have something to recess the flywheel into if you trimmed the corner supports), but otherwise an old Wilesco seem like an absolutely perfect pre-made terrain bit. Just needs a bit of paint.
