this is a lot of 4 plasticville buildings in ho scale, the first is the school which is red with the white roof. it is in very good condition with no broken or missing parts just a little dirty. next is the barn with silo it is brown with gray roof. the left side roof was broke and reglued but you can still see a line where it was broken.next is the cape cod house it is off white with brown trim it is missing 1 window on the left side. last is the service / gas station it is missing the doors and what ever was supposed to go in the front window there is also some discoloring on the roof. some of these buildings have a patent date of 1952 on them. but i do not know how old they are.
