Andrew,
Very interesting! I had not attempted to put this style on a triple air intake as the proud flange looked like it would cause a problem. Does this mean that the body is a smaller diameter? I have access to most, if not all, of the types under discussion and I intended to get to them this afternoon to take some comparison images, but my day did not go as planned (hopefully tomorrow).
Here are some images from 1947 and 1949 GM Diesel Industrial model parts books, and a 1957 Detroit Diesel parts book, showing various evolutions of air cleaners. I note that for both the AC and Donaldson types, the holes moved from the lower housing/shell in the wartime parts books to the upper element assembly in the post-war parts books (that I can access).
