In Memoriam

Klaas Willem Jonker
(Wilko)
† 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.

Van Berkel WA

In service with RNlNAS.

The first production machine was transferred to the RNlNAS in September 1919.
Twenty of the thirty-five aircraft were intended for use in the Netherlands East Indies and received the registrations W.1 to W20.

The planes to be used in the Netherlands were registered W51 to W65. The registrations were not parallel with the construction numbers.
Technical Support is also built five machines from components supplied, these were the records W66 to W70.

The technical service of the RNlNAS had built several complete fuselages, which needed just to be mounted an applied with a serial of the original aircraft. To avoid problems with the license rights, also a few parts of the original device were added.

From October 1924 all remaining aircraft in the Netherlands had their fuselages replaced with a fuselage made of tubular steel instead of wood.
These fuselages were built at the Naval Air Station De Kooy, also the losses were compensated.
The rudder was enlarged to improve some of the water manoeuvrability. Also, the engines were replaced by BMW III engine, the cooler on the wing leading edge was moved to the nose.
The wooden floats were replaced with aluminium ones.
