Thanks for the graphics from FAOW.
Another good source of images for the Nell is here:

There are some very nice pictures from a WW2 era Japanese magazine (Asahi Graph) which show unusual interior details.
Still not enough to really model the interior of the plane, but pretty close.
What's lacking are details of the ventral turret (or the "dustbin" turret in the early marks of the G3M1) and more detailed views of the interior of the various crew positions (notably the bombardier's station). Details of the wheel wells and the shackles for bombs and torpedoes would also be helpful.
