That appears to be a lightly modified common Navy "Chart Plotting Board" used on airplanes that went through several marks, Mk 3, Mk 5 Mk 6 etc. The instructions for these boards are for solving many vector diagram problems necessary in flight. I looked at my instructions and nothing about collision avoidance. But they do describe who to set up and use the board and you can easily figure out how to use if for collision avoidabce.
