TheBeast Greetings.
Download and install this excellent mod and I noticed I had some of the textures with the name Conning_7C_02_albrecht_bak.dds, which is the texture of the guard tower, I took the liberty to use his original textures of the old tower to the hull of submarine.
Add fasteners as the original submarine, of course, still much work ...
I am posting some shots of my work, yours included and if you will permit me, I'll keep working on these textures, of course, always with his credits include ...
Thanks and congratulations for this good job ...
Sorry for my poor English, I am using a translator for correction of my spelling errors ...
