The book, Fokker Eindecker In Action (# 158) represents a pictorial review of Germany's first purpose-built World War I era fighter and the first aircraft to be fitted with synchronizer gear, which enabled the pilot to fire a machine gun through the arc of the propeller without damaging the blades.  The Fokker Eindecker was developed and built by Dutch designer Anthony Fokker.  The Fokker Eindecker variants granted the German Air Service effective air superiority over Allied aircraft from its introduction in July 1915 through early 1916 when newer British and French aircraft leveled the playing field.  The Fokker Eindecker was used throughout the remainder of World War I but was effectively obsolete by the middle of World War I.  The Fokker Eindecker carried one pilot, had a top speed of 87 mph and carried from one to three 7.92 mm MG14 machine guns.  The major sections of "Fokker Eindecker In Action (# 158)" are as follows: 1) Introduction; 2) The Fokker M.5 (Eindecker I); 3) Fokker M.14 (Eindecker II); 4) The Fokker M.14 V (Eindecker E.III); 5) UPAVON Report No. 48; 6) Fokker M.15 (Eindecker IV); 7) German Navy Eindeckers and 8) Other German Monoplanes.  In addition to an informative narrative, "Fokker Eindecker In Action (# 158)" includes the following features: 1) Approximately 96 black and white vintage photographs; 2) About 25 black and white illustrations; 3) 10 color side aircraft profile illustrations; 4) 1 three-view Fokker M.5 L (A.II) black and white illustration with specifications; 5) 1 three-view Fokker M.5 K / MG (E.1) black and white illustration with specifications; 6) 1 three-view Fokker M.14 V (E.III) black and white illustration with specifications; 7) 1 three-view Fokker M.15 (E.IV) black and white illustration with specifications and 8) 3 color cover paintings.  This book is 50 pages and is in excellent condition.  The author is D.
