[2] Barker involved himself in the kind of rough-housing that became the hallmark of the group and later recalled that "I used to go out with the boys to Hyde Park and we had many rows with the Reds.

[2] In 1927, he was brought before the Old Bailey on charges of possessing a forged firearm certificate after Rippon Seymour had pulled Barker's revolver on another member, Charles Eyres, in a dispute over party funds.

[6] In 1929, Barker was arrested at the Regent Palace Hotel, London, for contempt of court for failing to appear in connection with the bankruptcy proceedings.

The probate notice refers to Lillias Irma Valerie Arkell-Smith or Geoffrey Norton, married woman, with an address in Kessingland, Suffolk.

[11] D. H. Lawrence, in the essay "A Propos of Lady Chatterley's Lover" (1929), described Barker as having "married a wife and lived five years with her in 'conjugal happiness'.

Brighton Museum and History Centre marked his life during February 2006, as part of England's LGBT month's celebrations.
