I'd search for one of the J. Novotny drillings with at least one of the tubes being paradox: http://forums.nitroexpress.com/showflat.php?Cat=0&Number=20443&an=0&page=23&vc=1 .

If you aren't a member you can't view the site. I can post images if anyone has an interest.

Also Geno had posted a J. Novotny with a single paradox tube:
