This may be easy. On large WW II ships, the heading is distributed to a
multitude of remote indicators as Synchro signals from the Gyrocompass,
incluging the guns and the Dead Recconing System. A simple 5 wire cable
could get that heading information to an encoding box.

At a guess, the ncoding bx would have had two inputs; one from the
yrocompass, and one from the antenna azimuth. Their relative position
would have deriven the encoder wheel.

FWIW,
