I restored one of the world war II cameras with the 1846 tube and it works remarkably well, but requires an enormous amount of light. Pretty good picture out of doors in full sunlight; indoors, not too happy. I'd suggest, if you'd like, get hold of one of the old cameras and bring it up to snuff. It's an easy matter to change the vertical and horizontal scanning rates to fit NTSC or PAL standard rates. The only thing you'll really have to build from scratch is a filament and B+ power supply, so you don't have to deal with the original 400~ supply used in WW2.
The Japanese gentleman who built a modern version from scratch is a renown, very high end engineer who did custom jobs for Sony and others. He is NOT your average amateur, so I'd think twice before trying to tackle this job from scratch!
Good luck
