I found this on page 72 of the Spring 1962 edition. It is a photograph and caption accompanying an article on WW I triplanes. I have it scanned as a much larger file, but the resolution improvement is negligible.
I have looked through the Winter 1961-1962, Spring 1962, Summer 1962, and Fall 1962 editions of Air Progress, which is as "current" as my collection goes, and not found an article on this airplane. Frankly, while there are many unusual and "one-off" aircraft illustrated in these magazines, I would be surprised if so obscure an airplane as the Breda-Pensuti would have merited a full article. Perhaps Italian publications would be better sources.
