The window looked a lot like the others on the caboose. But looking through it you could see the image would be degraded. You have to be careful taking the caboose apart as there is a fair amount of wiring to be considered. We found the truck locations were not optomized to allow the four long screws to be removed easily. However the end result justified the labor. I am a photographer and spend thousands on very clear glass for my lenses. Model plastic just does not do the trick.
