Is the Tamiya 1/350 Missouri with the correct full hull?
Correct as in; is it a full hull? It is a full hull, I have no idea if it isn’t correct or not. I haven’t heard anything to the contrary.
Full. 
If remembered right there was a comment that it is not a complete full hull so I was thinking that it needs to be corrected, more bottom perhaps?
You may be confusing the 1/350 kit with the 1/700 kit.
The 1/350 kit has a full hull.

The 1/700 kit is a waterline kit

Or are you perhaps thinking of the old Revell kit which has the flat-bottomed hull?
Some Revell kits came with incomplete below the waterline hulls- Tanker Glasgow, Steamship Hawaiian Pilot are examples.
There WAS a confusing thread a few months back about this, but the kit does come with a full hull.
What I am asking actually is if the full hull of the Tamiya 1/350 USS Missouri is the correct shape. I’m sorry for the confusion.
The Missouri has been out for many years and I have never heard any complaints about the hull.
