I binned mine in '89 and have never seen one in a crew room or flight deck since.
I cannot believe that the CAA still insist on this antique rubbish, they should be ashamed of themselves.
I suspect that most current ATPL/Airline Pilots (myself included) would fail the exam miserably. However, you can't argue with tradition. Those NDB approaches and holds are sure to make a comeback......
Anyone remember Decca?
