Tillage parts labeled as "New Old Stock" are from various manufacturers. These items will fit and function correctly but vary in color or slightly in shape due each manufacturer's unique pattern. They could be from the original equipment manufacturer or any number of aftermarket suppliers such as Weise, Adams, Osmundson, Crescent Forge, Veldmaster, Star, S&J Kitchin, Hamburg Plow, King Plow, C.F.C., Herschel, and others.  Some of these parts have been out of production for many decades. The brand of tillage parts will vary as inventory is acquired.   There may be some surface rust due to long term prior storage.
