I received my 8R from a coworker in Denver in 1993. I believe he purchased it new, and used it for years before generously passing it along to me. I’ve used it off and on since then. It has always been reliable and convenient. I’m hoping to pass it on to one of my sons someday... when I’m done with it of course. Guess I ought to clean it up sometime ;^) Any guess on the year based on the sticker? I have no idea.
