Plate Burr - I think it's 24 pieces, if I counted right. It's large, 5 inches wide. Very similar to the Chicago Puzzle and Novelty #3080, although I suspect that the one offered in the catalog was much smaller. This has the look and feel of an Arjeu puzzle, although I could find nothing that indicates that it is from Arjeu. So: I don't know the designer or manufacturer, or where I acquired it. I've owned it about 20 years, more or less.
