Now maybe this goes into pre1900 if so I apologize. But this is mostly about WWII. Lets say that the orginal CSA was able to seperate peacefully and the US and CS are allies in WWII. Now lets not talk about the odds of this happening just what would be if the countries were like the map below. What would the CSA's main areas of industry be. And would they use the same equipment as the US or would they have their own gun companies in the south.
