ZS-BNL  Vickers 635 Viking 1B                                    (c/n  297)

                              

                                  Here's a much better image of a SAA Viking, taken in the late 1940s, just before it was sold to
                                  BEA as G-AMGI.    Like many of its breed it wound up with Eagle Aviation, and this one served
                                  for a while as a cabin crew trainer before being broken up at Heathrow in 1960.
