Thanks guys. I do have some of the ExactRails, I also have a few of the LBFs that I want to bring up to the level of the ExactRails. The LBFs have cast-on ladders and crude stirrups, which I'd like to replace with finer parts. However I must have been half-asleep when I posted the pics, as I just noticed now that they show different ladder styles. The first pic is like the LBF car, and the second is like the ExactRail.
On that second pic, those areas of very light gray on the roof are kinda interesting. What exactly is that? It doesn't look like over-spay to me.
These cars have little rust, but the graffiti can be fairly elaborate.
