Hi Wagner, The Markings on your Dagger indicate a Luftwaffe Company headquartered in Henkenhagen, near Kolberg / F. L. Kp 40 = Flugmelde-Leit Kompanie 40. It is quite interesting! I have seen 1st Lufts and Luft Swords with markings like this when a dagger was owned by a training Squadron and issued / "Loaned out" to Cadets for use on dress Occasions but when they did not own one of their own. This is the first 2nd Luft I have seen marked like this. Very Rare type Marking and a Buchel to boot! Congrats!
