Undefined Advances

Having knocked up a few fighting compartments for the Basilisks, I ended up with several very bare sides for the fighting compartments. What do real SPGs have? Stowage and boxes for stowage on the sides, of course. So I took a couple of bits of Lego (pics 1 & 2), and boxed them up with plasticard (pic 3). On the Wild West front, I cut up a spot of balsa, and then glued and nailed it together (pics 4 and 5). What am I about? Well, what does a cowboy need that ain't a cow? A horse, of course. Enjoy, people!
