Rabe & Peter,

According to Mombeek in Jagdwaffe, Luftwaffe Colours Vol. 1, No. 3 Hrabak became Adjutant of I./JG 138 (later I./JG 134) on 1 April 38 and was appointed Staffelkapitän of 1./JG 134 (later 1./JG 76) on 1 Jan 39. This latter date is also found in Obermaier's Die Ritterkreuzträger der Luftwaffe as well as in Prien's Der Jagdflieger Verbände...Teil 1.
So I am curious about the source of your information.

Tom
