[WWI] ID needed

[Diego Fernetti]

Hey!
In the "Landships" forum someone asked for any identification of the flag
sported by these airplanes in a demobilization depot in 1919 (see
http://www.activeboard.com/forum.spark?forumID=63528&p=3&topicID=14966402 )
I think that these fuselages are from Albatros J types... is there any clue
to know the colours of the crossed "flags" on their sides?
Thanks in advance for the help.
