this is a beautiful old set, guaranteed for one year by a company that ddint list a zip code, so that means in the 1950s or early 60s, the guarantee must be expired. there are six precision aluminum beams and five required precision knurled screws to connect them making six feet two inches. one trammell has a point with knurl nut fro adjusting the other has a replaceable lead point for drawing, both have locking features as would be expected. the bottom box is not ripped, there are a few tears in the top, for all your six foot circle or arc needs! the set has no rust or corrosion and will be carefully packaged for shipping. weighs almost two pounds and will ship at three, as always free pickup is ok on long island. thanks for looking at this vintage tool.
