I didn't do too much painting to the interior since most of it will be hidden. I did try my hand at making some decals with my Alps printer. I made some placards, more to test out the possibilities than anything else. You can see a couple of them next to the divers station, and another on the rear bulkhead. I also labeled the periscope boxes that are on top of the gearbox, again, just to test out what I could do for future projects.
