This is a 1/144 scale version of the re-entry vehicle from the Hawk Manned Orbiting Laboratory kit. There are two vehicles per print.
To keep the costs down, the walls are very thin and delicate. If you plan on sanding the outer surface, consider filling the interior with a support material and handle the sanding very carefully.
