Retaining wall, cut stone. Package of three realistic cut stone HO scale retaining walls typically found alongside of tunnel portals to hold back precipitous terrain. Pure white hydrocal plaster castings require coloring with water-based paint wash or Woodland Scenics liquid pigments (a dab of black and gray in water for these).
