I doubt there will be one for another type of VII that's why I'm suggesting it might actually work. Have a look in this thread
http://www.subsim.com/radioroom/showthread.php?t=88849 and see what types of skins exist. If you need any one in particular let me know and I'll upload it for you. I have quite a few skins for VII type boats on my installation so tell me which one you like (or even style, colour etc) and I'll send it to you. Just make sure you enable them via JSGME
