I got this model from a private individual, the windows were missing, and it was complete with light kit and fittings.
I painted the hull elements separately before assembly and assembly and the first mistake. This was supposed to be bronze colored and I made it copper colored. Before assembling the hull I integrated the interior and lighting kit and used pigments for the aging and corrosion of the ship. Paint the octopus, etc. …..
For support, I remembered the books I read when I was young 🙂 by Jules Verne. I put the Nautilus on a book I made myself out of foam board.
