Since most people will probably not have a Set 77904 hanging around to modify, I’ve built the parts list as a ground-up list, not just the pieces needed in addition to Set 77904. As such I’m calling this a modified build of Set 77904, since it uses more than 2/3 the pieces from that set as a skeleton for the additional hull plating. I wanted to do a Lego version of the Imperial Nebulon-B since I first saw EC Henry’s video, and Lego’s Set 77904 provided the perfect foundation. See EC Henry’s video “The IMPERIAL Nebulon-B Frigate (Fan design)” on YouTube.
His concept is that the Nebulon-B as it appears in the Star Wars movies is a ship design that the Empire rejected, and that the Rebel Alliance stole from a couple shipyards after they’d been scrapped for parts. This is my Lego adaptation of EC Henry’s design for the Imperial ‘variant’ of the Nebulon-B Frigate.
