I don’t doubt that, but the RAFA, which this thread is about, wasn’t formed until 1929.
From their website:
In 1929, in the Sergeants’ Mess at RAF Andover, three men named Vernon Goodhand, Joe Pearce and Warrant Officer Bartlett met to discuss the formation of a single organisation dedicated to the welfare of serving and ex-serving RAF personnel: one which would replace the many smaller organisations that had grown to keep former servicemen in touch since the end of the First World War.
