Added a brief section on the history of this camera; the statement that it was released in 1951 (or c. 1950, as in the linked article) doesn't match with newspaper adverts of the time, which show it being available new from at least 1946 through to 1955 - Triluminary (talk) 12:16, 30 June 2021 (UTC)
Added a new section on the popularity of the Kershaw Penguin based on Vaughan's 2013 book on Kershaw cameras Triluminary (talk) 20:35, 1 July 2021 (UTC)
