Grew up down the street from the Linn tractor plant, where many relatives and neighbors once worked, and next door to a Linn/Frink Sno-plow/Walter truck agency. I do free look ups of serial numbers, photographic recognition and advise on any Linn related questions you might have, and generally like to locate/excavate/photograph/identify old iron for fun.
