Hi, the pictures show a very home made control system , I know what it did or at least was supposed to do but thought I would put it up here to see if anyone can guess. Part of this was replaced with a more modern system..


And a Brucie bonus point if you can tell me the model !!

Looking at the microswitches worked by the cam on the rudder servo, guessing that there was an arrangement to reverse the inboard motor on full rudder to improve manoevering.  I seem to recall a magazine article doing something like this a lot of years ago.  The other grey panel could be on-off-reverse switching for two motors? 
Impressive bit of electro-mechanical engineering of its time there.  Probably two ESCs and a mixer nowadays.

Hi
Yes more or less, unfortunately never seen it working but from what I was told it basically made turning the Bismark a lot easier
by controlling the motors when the rudder turned Port or Starboard .
The section with the cut out actually housed a large Flash unit from a camera which by the use of small mirrors simulated I assume explosions on the ship.
She has now been fitted out with more modern equipment but I kept the old electrics, one day I might try to set it up working.
