Yes, Bill is a pro modelmaker, but he is also a big scifi fan and builds models from scratch just cuz.
Here's an article on Modeler Magic about his recent project to build a replica of Lost In Space's
Jupiter 2. Bill's model is pretty unique in that its exterior is based on the full size standing setpiece used in various episodes of the show, rather than the filming miniatures. It also has a complete control deck interior, and he built a bunch of at-scale bits of furniture and equipment seen outside the ship.
