In [this community question](https://mathoverflow.net/questions/309650/what-are-examples-of-books-which-teach-the-practice-of-mathematics) asking about books that teach the practice of mathematics, the author mentions the works of [W W Sawyer](https://en.wikipedia.org/wiki/Walter_Warwick_Sawyer).

Which of Sawyer's books were translated into languages other than English, and what are the publication details?

His [Wikipedia page](https://en.wikipedia.org/wiki/Walter_Warwick_Sawyer) states that his books *Mathematician's Delight* and *Prelude to Mathematics* "have been translated into many languages", but I have been unable to find publication details for any non-English language edition of even a single book of his. The cited source is an article by Ailsa Ferguson published by the University of Toronto (thanks, @Igor Khavkine, for tracking this down at Archive.org) which states that *MD* was translated into 10 languages and *PtM* into six, but that's all I know at the moment.
