There may have been mistakes made in creation of data modules (pretty much all hand-made). I fixed Module:I-19.

I renamed it Type B because the japanese name for the class is just Type B, and [Wikipedia:Type B submarine] calls it just Type B as well (as opposed to Type B Mod. 1/2). I was unable to discover a basis for Type B1.
