The real Ger/CB/1937 14in still works pretty well
The real Ger/CB/1937 14in specification works well in Springsharp. The only knock on it is that it "tends to be wet forward". I converted the 15in Springsharp to the 14in version, and found that it worked "out of the box". I reduced the belt length, as it was longer than needed and raised the freeboard. That necessitated reducing the range. That may have been a waste, as I did not change the "wet forward" complaint. This is the Springsharp report:
