KADLEC Instrumentenfabrik Prag was an instruments manufacturer located in the former Czechoslovakia, until the end of WWII.
There were two versions of the AK39 compass: a simple black one and a white/clear one with sighting aids. The abbreviation AK stands for Armband-Kompass (wrist compass) and the figure 39 probably designates the year of design, 1939. These compasses were designed to be worn on the right wrist/lower arm, over the flight jacket, or attached to a rescue vest. The letters Fl are an abbreviation of Fliegermaterial (aeronautical material).
