1. He 51 of JG 132 “Richtofen”, I. Gruppe, 2 Staffel. The Jagdgeschwader was broken down into two gruppes. The I. gruppe would have no extra markings, while the II. gruppe carried a bar below the cockpit. Each gruppe was then divided into three staffels. These are distinguished as 1 & 4 staffel – no marking, 2 & 5 staffel – stripe on nose and rear fuselage; 3 & 6 staffels – disc on nose and rear fuselage. Hence an aircraft carrying no bar, but a stripe on the fuselage is from the 2 staffel, of the I. Gruppe.
