Thanks to the clever and persistent efforts of Kenny (AFGP9) we now know that the article on KleerPak's was published in the September 2016 issue of CTT. It is a good article worth reading. That article references an earlier one by Bob Tufts in the January/February 2005 issue of the S Gaugian. I have both of these magazines. If anyone wants to read the two articles and does not have access to those issues let me know and I will try to post them here.
