I'm working on a version of a spread card for SH4. I'm not sure if this was a standard issue, or whether it was something made up by the crew. As the TDC could not generate spread angles, it was up to the crew to calculate them, using simplified maths, or matching by hand the bearings on the TDC, as used by Dick O'Kane, or by calculating gizmos that they made up. There is a spread angle calculator card in the USS Torsk that is a graphical means of calculating the spread required at variable torpedo tracks and at variable torpedo run length for variable target lengths. It's a recreation of this that I'm working on.
