Thanks for the images.
I now think that I have confused the issue from the original thread posting.
I had thought that the referred to signal reverser was for track circuited control to return the signal to stop in lieu of the signal box frame lever.
I am now getting the impression that it is to provide electric contact circuits to the repeater indication in the signal box.
I am guessing from the images that the particular semaphore is a lower quadrant.
I will now need to google for any working diagram details for our NSWR track circuited lower quads to ascertain just what was inside the box attached.
