MR VISSER
Mr Chairman, my instructions from Lieutenant Shaw and Colonel Erasmus is that, looking at the floor plan of the 5th floor, the marks made there represent a trellace, 'n traaliwerk, with a door, a security door and it was exactly at the time in 1986 there was a similar trellace on the 4th floor.
    So both the floors had at the same  security entrance as it were, from the lift well.  Shall we, perhaps, give this an exhibit number, Mr Chairman.
