The World's first aeroplanes armed with a true gun synchronisation system, early victories in the hands of Germany's fledgling fighter pilots gave the Allies serious cause for concern.In this study, Peter Grosz consolidates his Datafile coverage of the Fokker Eindeckers-with the reprinted Datafile 15,to present this true account of the development of Fokkers' synchronising system for the first time,stripping away the myths that have mired this history for many years.Over 75 rare photos, detailed scale drawings and authentic colour notes and rear cover profiles complete this historically important study.
