In the second volume of this publication, the remainder of the Opel
motor company major production types are covered that were not covered
in volume 1, such as the Opel P-4 that was also used as the basis of
many of the pre-war mock-up training tanks used by the German army due
to the lack of real tanks to train with. The "Opel Kadett" (cadet), the
Opel Supper 6, the "Opel Kapitan" (Captain) and the top of the range,
the luxurious Opel Admiral.
In this volume the author provides a detailed impression of these
vehicles through original photographs, taken both during and before the
war by the normal German soldiers who both used and served with these
now classic automobiles.
