Hi EmeAzu,
o.k. here is a screenshot of the skins for AG124's ECT and CHT:

With the grey skin for the tanker you can use this ship in navy conoys (looks very good with some cruiser, destroyer and so on).
It is very easy to rename a ship. You just need Pack3D - that's all Just make a complete copy of the folder where you ship is in. Open the ship_name.dat file in this folder with Pack3D, press the "Clone"-button - and exit. Then rename all the files in this folder to the new name you want to have (for example: NCHT*.* --> NKDF*.*). Don't forget the *.cfg files in the Roster folders (the nations where that ship is in use). And don't forget to edit both *cfg files - change the ClassName=+.
In this way you can easily duplicate a ship and/or give another name to that ship.
Hope it helps
