I'm no expert here but from what i've read here and there both US and German had AoB calculator rulers. However, at least americans (not sure about germans, although i recall reading that some did the same) were used to eyeball it (faster and rely mostly on your skill rather than knowing ship length and height).
If my memories don't trick me japanese had a device in the periscope to help them to ESTIMATE it.

Consider that calculating a fire solution was not something that you set once and you are ready to go, it requires constant updates so eyeball it was the fastest way to gather it.
