I have seen a photo in an album (B&W) of a SE 5a. late 1917 or 1918 with.
White(ish)
Wings upper and lower, top and bottom: :White
Tail fin, Rudder and horizontal stabiliser, or rear wing: White
Wheel hubs white. : White
Dark-( Dk Green?)
Fuselage

ark
Wheel and Wing struts: Dark.
Note.
No serial number, or national marking on wings or tail.
No guns.
A half circle screen for pilot.
No hump behind the pilot.
When would this likely have happened, new build from the factory, or after major repair, recovering?
There appears to be the top wing of another aircraft in the back ground of the photo in Dark(gr) with roundels, so likely British.
