Well;
I am going to answer that question for you. He is the guy that was mainly responsible for Disney's version of Jules Vernes " Nautilus" Now, Harper was prolific in that stuff. But, Did you know the Disney Sub in NO WAY resembles the actual description given By the writer in the story!
There have been garage and small company models. Some very big, and some small. But there's only one that even comes close and that one doesn't rate a cigarillo! Yeah, The Revell snapper! Now that one at least gives you a nice colorful interior to cut and fold inside where you can see in.
Do you know what a weaving shuttle is? No? Well, don't worry, I don't expect you to know this. Most folks don't . A weaving Shuttle is a two ended cylinder or oval shaped tool to pull the "Weft" through from one side to the other in a loom. The weft is the cross thread! It comes to a point on both ends. ( My late second Wife's hobby)
That's what the description of the Nautilus's basic shape was. Remember this was Early in Victorian times. What would've been her power source? Steam! Yes, produced by a star stone! What's that you ask? Who knows? Also, you have those nice lounge windows.
Now here's a No, No! They are Multi - Paned, almost like a faceted jewel. That wouldn't work at the depths she went! an OVAL port that is slightly bubbled and definitely has no sharp corners is what would work. Remember the foofura over the shape of windows on a certain passenger jet. They were square and some planes augered in, because of Fuselage failures related to those windows.
You Cannot pressurize and de-pressurize a container with square windows because eventually they fatigue in the corners. The same with those incredubly beautiful windows in her sides. Also Mr. Verne describes her as having a smooth surface like a porpoise to allow fast movement through the oceans and the ships they rammed!
Also the prop and rudders would've been protected better than the Goff Model. I will say this. Harper Goff will go down in history for all the eye candy he gave us through Disney and other Studios. The Nautilus will too. I do believe all faults aside, in many ways Harper captured the Victorian Mood with all the Iron Plates and Rivets though!
The vessel that immediately comes to mind when you say her name is not the Navy sub with that name but, Harper's version! So be it! I love it anyway!
