Howdy. I got a couple boxes out and looked at what I had. My 617 has a newer style label and includes a QR code. My 2015 year 686 has the newer style label, but no QR code. So, your label would seem to indicate a manufacture date of 2269, or September 25 of 2012 OR 2002. The -6 version has been around since 2001 per the scsw, however, it doesn't show the "CTK" serial prefix being used in either year. That's as good as I can do. Good luck!
