Charles ffoulkes contacted Gray initially to ask for any anti-aircraft drawings he might have which could be of interest to the Museum. Gray's two paintings on the subject were already sold, but the Museum commissioned copies of them (IWM:ART 320 and 321). The pictures were exhibited at the Imperial War Exhibition at the Royal Academy in January 1918.
In response to a request for further particulars about the subject matter, Gray sent in details and keys for the two works (30-33).
A further painting, 'A Factory During an Air Raid', was declined in June 1919.
Other matters include reproduction requests, Gray's involvement with arrangements for Connard's pictures included in the Sea Power exhibition in 1919, and the assignation of copyright in 1929.
