Yes, the original Excelsior-design. I might be remembering wrong, but I did not notice this when I last used her.
I'm not sure if the same texture error is also present on the 1701-B-model ("Excelsior Refit"), but it would seem likely given that this part of the model should not be different. If necessary, I can take a look and report back.
Now I get what you mean with "SFS" hull. I hope the devs will, too.
