The houses are 1:87 scale. I'm not sure if they are still in production or not. I picked up all 5 at a train show real cheap. They're all right out of the box with a few minor modifications. I took pictures while I was building them.
Alcohol will take some primers off. I usually use oven cleaner to take paint off. I like Mr. Muscle. The only place I've been able to find it lately is Ace Hardware.
