Aircraft Parts Manufacturer and "SkyBox" freight cars.

Here's an SP car that I scratchbuilt out of styrene from my own measurements and drawing:     These have always been graffiti magnets, since they have a large uninterrupted side surface. I built this in the late 1980s, before tag-style graffiti became available on decal sets. I need to update this with some of those.
