Richard,

This is the reference I was referring to. It is photocopied from a
book entirely about aircraft markings but unfortunately I do not know
the book's name, but it had a n individual section for every country
and spanned from the turn of the century to the late 1960's. This
passage is taken from a 236 page section simply titled "Chronology"
which started on page 171 and itemized all significant changes by
date. Any information about this or the white disc with a black
centre you mentioned earlier would be appreciated.

The entry for 12 Sep 1916 is this:

Special national insignia for British night flying aircraft
promulgated to all RFC units in an instruction which read:
The attention of all concerned is directed to the following
distinctive marking, which it has been decided shall be adopted for
black-winged night flying aeroplanes : On top and bottom wings, white
circle the same size as the blue circle used in the marking of day
machines.


So it just sounds like the upper wing roundel outer dark blue was painted
white but no mention of whether the dull red centre was over-painted in
black. They should really say "outer ring" as this would give understanding
to having a hollow centre of some other colour.

I think it's time to go to the boys who know!

If they're anything like the RAF Museum, you should be sent loads of stuff
through the post by very nice people.

Good luck!
