Looking at the Army Base, someone must have taken the tank from a different game and rut it into this one because there are to many vertices in it. In the NIF it has 'org_Arms v2 missile'. A biplane would have to be found and transferred to the Air Base.
Did the base show up, or was it just a note from the game?
As to a base name, the 5 windows or the three center ones could be removed and the name put in there. The DIFF and the NORM would have to be edited. On your map, unless you want the industry pic and the Report pic changed, that's 3 files for each. The rest of the needed files would be shared.
I don't remember much about the port problem, but again, the ship would have to be pulled from a different game. Do you remember if there were any port industries that DID work in maps? (just asking)
You might use the base without the tanks and just use names on the bases and maybe color to represent the different bases. If you are placing them, a naval base 'near' the coast would work fine too.
