In that particular video Mr. Dunlop, credited a man named Stan Hansen, and is seen using his device in the video, whom he had known as a peer in the gunsmith community and whom had designed a "block" of steel that was adjustable to remove the action slide sleeve screw cap from Model 12 (12,16 & 20 gauge) as well as Model 42 (410 styled Model 12).......in the 1960's !.........,apparently, according to Bob Dunlap in that video, Mr. Hansen's design had been hijacked by some folks at Brownell's and his "block" was never seen again........after hearing that story on the video, I researched the name on the internet and found Mr. Hansen, after 45 + years, in Benkelmen, Nebraska of all places.....so, I called him out of the blue this year and indeed, the story was true........I was interested in having a nice device to remove the screw cap from the Model 12 / 42's, as the factory had used a wooden "wrench" and a bench block to perform the maneuver......Mr. Hansen was quite surprised after almost half a century that anyone would have an interest in his design, so I persuaded him and commissioned him to get back to his machinist roots and make some 2009 versions of his device....after a month or so of contemplation, he called me and said "they were ready"..... each one, monogrammed and serialized to boot.....a beautiful piece of close tolerance machined steel with hardened insets and fully adjustable...... a win - win for all parties involved. If anyone has any interest or in need of a great tool to address removing the Model 12 / 42 screw cap this is the device (not to be confused with the so-called forend "wrenches" which I have almost every one of), this tool is the real deal. There is always a story and always a trick in gunsmithing !
