Surely that game would have been in the Informant.
If you can’t get an answer from anywhere else, try calling the Cleveland Public Library, home of the John G. White collection of chess books and magazines.
Thanks for this information.
Three different sources all in agreement, and all differing with Nunn’s move order (for his game 16).
In the particular game position it does not seem to be a major distortion. Perhaps that is why Nunn did not sense anything was wrong after he transposed the two moves (if indeed he did – or whatever earlier source transposed them before Nunn received the game score).
