Thanks. I've been using a model hanging in a museum for most of my reference. Some of it is mostly eyeballing.
Last night I added the emergency airlock. Attachment not found.
Some renders. I may have the antenna the wrong size. I modeled it separately from the rest of the model. Different lenses give it different scale. These are 50mm shots.
Since seeing the 1/144 scale plastic models of this ship on YouTube recently, I'm motivated again to finish this model. This is the exaggerated back end of the Discovery One ship so far.
