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.

Percival Proctor P.31 Mk.III and P.34 Mk.IV

History

The Percival Proctor was a development of the pre-war Gull. The prototype D.1 Gull (G-ABUR), a 3-seat tourer first appeared in 1932. The successor was D.2 designated Gull IV.
In 1934 Percival introduced the D.3 Gull VI, with a DH Gipsy Six engine, improved undercarriage and improved cabin layout (especially top and doors), but retained the Gull IV folding wing.
In November 1935, the four-seat K.1 Vega Gull was introduced, with a DH Gipsy Six engine and equipped with dual controls and flaps. This type was very successful and there were ninety examples built till July 1939.
The Proctor was originally a military version of the Vega Gull in which the number of seats was reduced to three. It was mainly used for training and communication work by the RAF, FAA and for air transport assistance.

Versions.

P.28 Proctor I:
was meant for communication purposes. The Navy version, Mk. Ia had room for a radio operator in the rear.
P.30 Proctor II:
was used by the FAA with the radio operator next to the pilot.
P.31 Proctor III:
Series 1 was used by the RAF as a three seat aircraft communications, and series 2 as a two seat radio trainer.
P.34 Proctor IV:
redesigned and returned to a four seat, with a longer and deeper body (and was initially called Precepter). This type was used as a three seat trainer or as four individual radio communications aircraft.
>Proctor V:
was a civilian version of the Proctor IV.

The production totalled 247 units of the Mk.I, 175 examples of the Mk.II, 437 examples of the Mk. III and 258 Mk.IVs and finally another 150 pieces of Mk.V. 
One single  Proctor VI float plane was manufactured in 1946 for the Hudson's Bay Company
