As we all know the great war ended in 1917 with an uneasy truce between the Entente Cordiale and the German Kaiser Reich. After the truce and perhaps goaded on by the Entente the Reich fell into a period of Civil war with the German democratic Kaiser Reich and the Austro-Bavarian house of Habsburg.
After the cease-fire accord of the Rheinbund the two warring parties fell into a cold war.
It was a time of mistrust but with the invention of the jet engine in 1970 the Reich was at the forefront of aircraft technology.
In the three pictures you see the latest Baade 187 of the Reichsluftwaffe, first flown in 1982 this ultra modern aircraft was technologically superior to the early model Messerschmidt-Benz 5109, however the surviving airframes were upgraded with a Siemens Turboprop beginning in 1983 and became again the mainstay of the AuBav Luftstreitmacht.
Still on the defensive though the AuBav were able to purchase the British Harland&Wulf 190 of the Royal flying corps making up the numbers to counterforce the Reichsluftwaffe.

Now then the planes in these three pictures are built up from different real aircraft, see if you can find them all.
