Pander S4 Postjager mystery logo


The Pander Postjager had a logo on the rear fuselage that has not been identified so far. Presented here is all the research material that I found. If you any idea, please contact me: Rob de Bie.





Amsterdam-Schiphol, 9 December 1933

The logo is hardly visible at departure, when it definitely already had it. That could hold a clue about the colors used. My best guess so far is blue and gold.



Roma-Centocelle, 9 December 1933

Refueling stop, at a rain-soaked airfield.



Tatanto-Grottaglie, 9 December 1933 - 27 December 1933

One engine ran dry of oil, requiring a long stay while waiting for a new engine to arrive from the USA.



Basrah, RAF RAF Shaibah, 28 December 1933

Refueling stop.



Dutch-Indies, 31 December 1933 en 6 January 1934

Destination.







Logos considered and rejected

My first guess was the logo of the organising commitee: 'Studie-comité Snelpost Nederland-Indië'. Its logo was a Postjager, not much point to paint that on the aircraft.





The 'Comité Vliegtocht Nederland-Indië' was another, older committee ( at least dating 1923), that gave general support only, and it had supported other flights. The logo was found on a letter reproduced on page 141 of Hooftman's book. But the shape does not match.





Stoomvaart Maatschappij 'Nederland' (SMN). Top: variations of the company logo (dating unknown), bottom the ship 'house flag'.







Koninklijke Paketvaart Maatschappij (KPM). Top: variations of the company logo, bottom the ship 'house flag' (1935 use confirmed).







Rotterdamse Lloyd. Top: company logo from 1947 or later, bottom the ship 'house flag' (1935 use confirmed).







Bataafsche Petroleum Maatschappij (BPM). Logo





Koninklyke Nederlandsch-Indische Luchtvaart Maatschappy (KNILM). Logo





Koninklijke Luchtvaart Maatschappij voor Nederland en Koloniën. Original name of KLM. Top: logo from 1932 letter by Plesman (28601). Bottom: logo on photo of ir. Wolff (RSL). Most unlikely to be used on the aircraft, since director Plesman did not believe in post flights, and saw them as competition for his lucrative post-carrying business.







The Rijks-Studiedienst voor de Luchtvaart (RSL) did not have a logo until years after WW2.





The Curtiss-Wright logo (copied from a lapel pin) might be a reasonable fit. But the location is not logical, why not apply these to the nacelles?





The Aeroshell logo would be an option, but does not match the shape.







This Dutch stamp design (Vliegende Duif) might also be a match. Despite the dove it has no link with air mail.





Yet another shape that possibly fits, but without the crown. If KLM is an option, than KNILM is another option. Or Bataafse Petroleum Maatschappij, or Luchtvaartafdeling (LVA)





A globe with the intended route, as seen in YouTube: 'KLM 18. London-Melbourne race' around 05:30, would be possible. However the continents in the Postjager photos do not match the pattern seen below.



Another helpful person noted that the upward-pointing wings resembled those seen on Hap Arnold's B-25, as seen here.





Drawing under construction

Starting with the Postjager drawing by C. ter Horst (NVM), I made a completely revised drawing based on research in archives. It's not done yet, so it's shown in a small size here.
