Yes, after a little effort, I managed to find a date for the journal in question :
After searching vor various terms and checking the page numbers, I think this is all the same volume, but I can’t be certain.
It passes the odd quarter-hour, the game of persuading Google Books to give you a date....

Edit 2: The copy of “The Rudder” in question appears to be 1955 - at least a search for “1955”, brought up a picture of the “masthead”. Why is it that Google books will show you only three snippets and then some, or even all of them do not show the term you were looking for? Is the search facility deliberately broken for copyright reasons? It’s OK if you are treating the hunt for a date like some literary form of Sudoku, but otherwise it must be pretty frustrating.
