Just puzzled by the shape of my 1970s cistern. I am re-furbing a
downstairs toilet and noticed that the existing cistern has a
kind of curved cut-out in the back at the top left hand side.
This can be clearly seen in the picture below:

Our 1970 Twyford's has the same cutout in the back
wall, but more or less in the centre. Don't know
what it's there for though.
