Sorry to see that you are now passing on this build Paddy. I know you have the skill to make a silk purse out of this sow's ear. I also know that at some point you have to decide if the juice is worth the squeeze.
What you stated on this kit is why some of my kits have never seen the light of day. I have one though that I am planning on getting back into at some point in the near future.
It is another "terrible Trumpeter" kit, the USS Arizona. Literally every little detail that I looked into was incorrect. It was a good "base" to start with, but worked me to death on what I did do. It became a shelf queen as I wanted to do some of the other group builds and thus has been on hiatus for 5 years. It is actually worse than what you are stating about this I am sure as I am going to have to rework the hull, turret faces, and am not even sure at this point what all else.
While I love the thought of large ship models, with Trumpeter's track record of half arsed research and poor execution, I just will never jump on another one of their large navel ships.
