His rules only cover WW1 era ships to like 1922 or something like that, so only the South Dakota class Montana would be available.
Yes. That is why I posed that question. That Company Alnavco made a model of this. I wanted their info where they got this idea from. They probably just did it because they thought it was neat.
As far as i'm concerned so long as the person building them can build them to the standard rules of the organization he/she is affiliated with and if it makes the person happy, why not, variety is the spice of life. Personally I would like to see a ship like that competing. It would be something different and have possibly a whole new set of challenges as far as the captain fighting with it and for the captains fighting against it.
