This auction is for 4 pre-built buildings for your model train layout that were made in the 1950's by Plasticville. I believe they are HO scale, but I'm not positive. See photos for measurements. All the buildings are in overall good condition. The Plasticville depot tower is in excellent condition. The roof of the TV station has been cracked and repaired and the sign with the call letters doesn't snap together tightly. The smaller part of the train depot come apart into 2 pieces. I believe these buildings are HO scale, but I'm not sure. See photos for measurements.
