Cornerstone usually provides a great quality kit. This particular casting had excess flash and a warped base causing the stairs to misalign. Roof pieces needed flash and tree mounts removed to fit properly.
Joints fitted together well. Design is efficient, minimizing glue joints. Windows are sheets, mounted on pegs, thus holding window frames in place and eliminating the chance of glue on the clear window. There is detail on the inside of the parapet walls, a nice touch. Decal signage is useful and varied.
This office will be used as a Shell tank farm office in a side track loading facility. Weathered the brick walls and enhanced mortar seams resulting in a very satisfactory addition to my layouts industrial area.
