In Memoriam

Klaas Willem Jonker
† April 30, 2018

On Monday 30 April 2018, Wilko Jonker died after a long illness at the age of 58. He leaves behind a wife and two children. The Dutch military aviation and plastic modeling were his hobby and on this website he shared all the knowledge he has collected over the years. His hobby has been able to distract him from the persistent disease in his body until the last week of his life. The contacts with other hobbyists were a major support for him.

This website will be maintained by different people for as long as possible, so that other enthusiasts can continue to benefit from extensive content.

Rumpler 6B-2


The Rumpler 6B-1 was originally a modified land plane and based upon the two seat Rumpler C.I

The modifications involved the wings position, an enlarged rudder and deletion of the seat of the observer.

During production an other modification was applied, the area of the horizontal tail surfaces was reduced.
The armament was one fixed forward firing Spandau LMG 08/15 fitted on the port side of the engine.


  • Rumpler 6B-1: the original version, 39 examples built.
  • Rumpler 6B-2: a version based on the larger Rumpler C.IV. Disadvantage was the lower performance. 49 examples were built.
