You are bidding on a circa 1980s era, lot of 4 stock or cattle cars in the picture with a red Katy, yellow Katy, Life Like Swift Live Stock Express, and brown Mantua Atlantic Coast Line. All are around 5 3/4 inches long. Light wear from use, red Katy is missing the brake wheel, appear complete otherwise, all could probably use some fine cleaning.  Zoom in for details.
