Hi...

Nice photo... an early version He111P. My initial thought was 'L1' (Lehrgeschwader 1), but admittedly, the character immediately to the left of the fuselage cross looks more like a letter 'F'. Bearing this in mind, I then thought of '2F', which was apparently an early coding for II.Gruppe/ KG28 up until September 1939, thereafter becoming II.Gruppe/KG54. This Gruppe continued to use '2F' after its redesignation until March 1940 when it began using the more familiar 'B3' code. The only problem, however, is the point you make about 7.Staffel which, of course, would have been part of III.Gruppe, not II.Gruppe.

Regards...
