This Dagger has a very interesting history, as it was presented to flyers were that posed as civilian aviators flying in a Sport club, because of the WW1 Treaty would not allow Germany to have a Air Force. Hilter used this LuftSport Club, to hide the fact that these flyers were actually training...
I think you have a late production 1936 DLV Dagger, with the wood handle and paint. The earlier 1934 had blue leather handle. The sheath would have been either blue leather or paint covering.
