Ken’s notes, however, clearly suggest that POW! editor was Bill Swallow, and mention at least one phone call from the man with instructions regarding Dare-A-Day Davy strip.
I ran a search for the name in the context of Odhams comics but Google returned no relevant hits. I also checked the Dictionary of British Comics Artists, Writers and Editors by Alan Clark, and there’s no mention of Bill Swallow there either. Was he perhaps a sub-editor in charge of POW! humour strips? Or maybe he was in fact the editor who chose (or was instructed) to remain anonymous because differently from the letters section, News from the Floor of 64 (the editorial column) went unsigned (I did check my copies of POW!).
