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.

North American B-25C/D and B-25J/K Mitchell: NEIAF

The aircraft delivered in March 1942 in India and Australia, had the orange triangle as national insigna applied. No photos of these aircraft in India are known. Only a series made at factory of North American. Soon the triangles were painted over with the Dutch flag.

The serials were applied according NEIAF (ML-KNIL) instructions, number on front of the wings and on the fuselage. No US number on the tail. In August 1942 these instruction were changed. The first six B-25’s in Australia carried serials like these instructions.

August 1942 and later the serials were carried near the flag on the fuselage. The US fiscal Year number was applied in yellow on the tail. (USAF standard).

May 1943 the instructions were change and new delivered B-25's had the serial in small whtie letters near the cockpit and sometimes in the sam fomat on the tail. (See photo page 177 in Camouflage en Kentekens). The serials near the flag were omitted. Older, remaining aircraft had these revised serialling applied after maintenance.

May 1944 serials were in large white letters on the nose and tail in US style type of lettering. Stripped (bare metal) aircraft had the serials applied in black.

From September 1945 a white frame was appied around the flags on camouflaged aircraft.

August 25, 1947 the serials on the tail was changed, in type I à 250 mm heigh for N5, and in type II à 19460 mm heigh, for the aircraft number.

At the end of 1947-early 1948 the flag was replaced with the roundel in six positions plus a small fin flash on the tail.

In January the serialling system was revised and change in M-serials. On existing aircraft the N5-codeletter was replaced with M and the number raised with 200.


All B-25's had the standard USAAF colour scheme of Dark Olive Drab, Shade 41 plus Neutral Grey Shade 43 applied. This scheme was referred to as shadow shading. The Dark Olive Drab faded quite quickly to several other colours like brownish yellow or grey, depending on the weather.
Propellers were overall black (Shade 44) with yellow (Identification Yellow Shade 48) tips à 10 cm.

End of September 1943 the code of the colour system was changed. Dark Olive Drab. Shade 43 became Dark Olive Drab, ANA 613 and Neutral Gray Shade 41 in Sea Gray, ANA 603. The colours itself didn't change.
The border between both colours was depending on where the aircraft was manufactured.

B25-C N5-145, is said to be painted all black, nick named "The Flying Dutchman" . [Personally I doubt this very much; The recently released Dutch Profile about the B-25 Mitchel states that none of the NEIAF Mitchells ever received an overall black scheme]

Early 1945 PEP started stripping the B-25's. Initally all TB-25's were stripped. Of other aircraft several parts were bare metal because of repairs, modification and maintenance.

From 1947 and on all aircraft had their camouflage paint removed during overhaul. In 1950 some Mitchells still had a partial camouflage.
