I've just made a discovery! If I had listened to others I might have found out long ago. As I've said, I've been trying to change the names of IABL's Merchant Fleet Mod ships in the Recognition Manual. I changed all the Display Names in all the British Roster files, to no avail. Then I had to change them all back. I did some looking online and discovered a conversation in an old thread, and Frau Kaleun kept insisting that it was all in the EnglishNames.cfg. So I sat down and started converting all those names. I started a test career and raced to the Channel, where there's lots of traffic, and she was right!
Here's the proof:
For each class name I used my own notes from the Ship Names mod, which includes a note for each name about how close it is to the model in question. I used the most accurate ship, or the largest number of ships in the listing for the class name. I used a separate class name for the 'X' ships. I also changed the name of Jimbuna's 'Q-Ship' mod, to make it even harder to avoid them (at least the first time).
I'm considering doing the same for all the ships in the game, but for now I think I'll release it the way it is. It isn't a mod as such, it's just a rewrite of the EnglishNames.cfg. If I made a new file it might not contain all the classes you already have, so I'm just putting it here so anyone can copy and paste it to their own EnglishNames.cfg.
WARNING: Do not make the change while at sea. I can tell you from experience that it will kill your career. You might not even want to do it in port, but rather wait until you start a new career. Anyway, here it is:
