I took a look at Die Flugzeuge der k.u.k. Luftfahrtruppe und Seeflieger 1914-1918 - there is a photo of A11, caption dates it from Spring 1917, has the 200hp Hiero - there does not appear to be red/white markings or crowns, just natural finish. The book also has a simple profile illustration with A11 in blue, captioned as flown by Banfield in Summer 1917 - couldn't find anything on A11 right now. HTH.
