  I am profoundly grateful to the individuals mentioned below for sharing the results of their research, which have enabled me to provide this information.  
  In the period early 1942 to early 1943 this HQ was probably one of the busiest and most important Luftwaffe HQs countering allied day-light operations.  Scores of RHUBARB and CIRCUS operations penetrated the sector of Jafü 2.  No wonder it was here that plotting and control procedures developed first.  
  Please note there were two airfields near St.-Pol.  St.-Pol-Bryas was a Feldflugplatz located just SW of the GefStd of Jafü 4 and St.-Pol- Nuncq with hard-surface runways, taxi-tracks and bunkers.

Chateau de Bryas, which no doubt initially served as GefStd before the transfer to the L 479.  The castle has a long history as military HQ in WW I, where it served as HQ for Marchal Foch and the UK 3 Army.




The GefStd was located in a L 479 (Jafü).  This was not identical to the L 479 used in the Flugmeldemess Stellungen.  Since the Jafü did not conduct Himmelbett, but Y-Verfahren (Jagd) only, the Seeburg Tische were not installed and there was thus no holes in the upper floor.

   I think this passage from Hoffmann II/1, p. 410, is of interest:  

"Der erste zentrale Gefechtsstand mit der gesamten Luflage auf einer Hauptlagenkarte entstand in St Pol bei dem damaligen Jafü 2.

Mit Hilfe von Stecklampen wurde der Flugweg auf einer Karte sichtbar gemacht. Das System wurde entwickelt und zum ersten Male praktisch eingesetzt beim Jagdgeschwader 2. Das System ist einfach und narrensicher und wird heute noch verwendet".

  The Flugüberwachungs Tafel (later Lagekarte) in Jafü 4, allied tracks have been plotted with Stecklampen (see below).  The map is mounted in the Klein FLUKO Raum, which must have moved to the Führungsraum.

  Jafü 4 was equipped with a very comprehensive radio system in order to ensure full radio coverage in the entire sector of responsibility.   As correctly described by Hoffmann above, Stab/JG 2 was also stationed at St.- Pol for a long time, and it was the development of the Stab GefStd that resulted in the establishment of the Jafü GefStd.
