Well all I've decided to give it a shot. I'm going to attemt a kitbash! I have decided to use an old Walthers HO North Island refinery for part of a madoern power plant that I'm building for my future (fingers crossed) layout. However, the power plant I'm basing my model on Is huge and boxy. What should I use for the boxy part? The refinery will be used for smokestacks etc.
