Hanson Irwin 10-piece screw extractor set, part number 53226, in the original plastic case and with instructions.  Sizes from 1/8 to 13/32".  The extractors look like new and have possibly never been used or at least much.  I see no damage to any of them.  The case has faded some from laying around for years, apparently near a window.  Included is a drill bit (3/16) that also looks new.  Made in the USA!
