Please help me with these old Duncan Yo-Yos, Canadian copies.

Well, I don’t come here that often, so sorry for the necro post.  If you’ve still got pictures somewhere I could check them against Lucky’s book.  I think it’s weird (and Chris Mikulin and others would say laughable) that the term “yo-yo” is still protected by trademark in Canada, even though the trademark holder does not produce any new yo-yo designs and does not participate in the community.  More information can be found at http://www.ic.gc.ca/app/opic-cipo/trdmrks/srch/viewTrademark.html?id=398669&lang=eng and http://www.yoyomuseum.com/museum_view.php?action=view&subaction=exhibit&exhibitid=2276.
