This 6231 1/2 from 1972. A real workhorse. As you can tell from the pocket wear, it was used and carried by someone most every day of its life. Once I took possession, it was apparent why it was someones trusty companion all of these years. The smoothest opening and closing action accompanied by that satistying snap. The pen blade has been worn and reprofiled some, but clip is quite full. Such a pleasure to use and carry.
