Hi Steve,
Effectively, on other available picture, the Arado is visible in far background.
Another much more interesting detail, if ever, is the fact that code number "Weisse 22" is situated at the right of the "black" cross; reading from left to right.
I.e. the cross on starboard is situated more aft on fuselage (or more forward on port) due to lesser space left by G-12 canopy.
Regards,
Franck.
PS; This feature raising a doubt concerning application of unit markings on that period machines for which only one side is known
