Newark was a regular contributor to Boys' World in 1963-64, especially the one-off "Hand of Fate" and "Ticket to Adventure" series.
He began writing for Commando with Born to Fly (224, 1966) and wrote a total of 21 stories, ending with Shooting Star (483) in 1970. Quite a few of his stories were reprinted in the mid- to late-1970s and one—Clash of Aces—was again reprinted very recently, #4326 in September 2010, as part of Commando's season of flying adventures, and in the collection Commando: Aces High!, also published in 2010.
Peter Newark now runs a historical picture library, The Historical Picture Service, based in Brentwood, Essex. His son, Tim, is also a journalist and historian, having written his first book, Medieval Warfare (Jupiter, 1979), whilst still at school.
