For your consideration, here is a Vintage EKCO Round Metal Apple Slicer Cutter Kitchen Utensil, made in the USA.  It measures 6 1/8 inches wide.  The diameter of the hole is 4 inches.  It has wear on it.  There are a couple of tarnish spots on it.  Nice heavy duty model that was built to last.  It will be mailed in a box for protection.  Item pictured is the actual item for up for sale and comes from a non-smoking household.  (634.7a21a-.8kx1)
