This is my interpretation of the re-entry vehicle from the Hawk Manned Orbiting Laboratory kit in 1/72 scale.
Note that the hatch is printed inside the model, on a sprue. The PA12 print may have the hatch slightly stuck to the interior. The hatch on my sample seems to be slightly smaller than the design; if build with the hatch closed, hold it in place from the inside with poster putty or tape before glueing.
I have a version with solid windows and closed hatch as well:
