Here is the link to that page http://www.marlinowners.com/forum/336/45356-marlin-s-texans.htmlOn the 336 Home page, look at the top where the stickies are. Find the one that says "Marlin's Texans". Open it and go down a bit, there is a pic of a 30TK.
The 30TK is actually a Marlin but was only marketed at KMart when it came out--so its kinda like the Glenfield line which mostly sold in regional stores and LGSs. The 30TexanK-MartI don't believe there is any such thing as a Glenfield 30TK, is there? The 30TK is labelled Marlin AFAIK.
