Answer to the second question. The Banner, Trumpeter and Hobby Boss kits of BB-39 in 1/350 scale are all the same kit.

As GM said, the 1/350 kits of the Arizona are from the same molds.  If you are interested in converting one to the USS Pennsylvania, Shapeways offers an excellent conversion set.

Hmm;

 I know of no one that does .I may be wrong .Now , I do remember REVELLS old Cruiser offerings of probably 1/535 or 1/400 .

Yes, Revell did some box scale US cruisers, as did Monogram, Lindberg, and Renwall. Aurora did one in 1/600 I believe as well. 

But, for a 1/350 US WWII cruiser, Trumpeter has announced upcoming releases of USS Baltimore and USS Pittsburgh. Or there are also the Academy & Trumpeter kits of USS Indianapolis, and Trumpeter USS San Francisco already available.
