KG III/355

[edNorth]

Well, its matter of writing. KG 355 yelded plenty responses whilst 'Giggling', then one can find info on III Gruppen *third Gruppen.

I think "flugaustrag" can indeed be training flight as date is between 'events' when Germany added terretories to its Fatherland, and rest is code for the individual aircraft.

Type be Heinkel He 111 *Arabic, not Roman figures, and code 55+O37 = 55 the fifth Bomber Geschwader (or Gruppen, or assigned unit to that Luftkreis) in Luftkreis 5, the individual letter O *Otto of seventh Staffeln in third Gruppe *they having Gruppe first, then Staffeln.

This later became KG 53, then getting codeA1 and summer 1939 is the time when this was done althoug I do not have exact date for KG 53, as it was not a Ju 88 unit. (55+O37 then theoretically becoming A1+OR )

Explained below.
