In excellent vintage condition and it is new and never used , circa 1980s . The bore hole is 1.25" with a step down ring to 30mm . This has spent its life collecting dust in a garage . In clean condition with some wrinkling of the paint on one side . Still has its original hot wax dip coating for protection on the carbide tips . It is approx 165mm diameter . Comes in original box . High quality and very expensive when new , not like the Chinese rubbish you can buy now .
What you see is what you get so do check all pictures thoroughly .
