Two minor historical errors.
1.) KG 1 abandoned the old coat of arms badge when the war began and would not reinstate a Geschwaderwappen until 1941 when it took on a simplified version of Paul von Hindenburg's signature. During the BoB only a few individual Staffeln were known to have sported a badge (i.e. 7./KG 1).
2.) I./KG 1 did not use the tactical code of a I. Gruppe until 1941 but continued to use the code of a IV. Gruppe as it had begun its life as IV./KG 255 before it was renamed I./KG 1.
