I figure this is a long shot, but...
I have a set but I am missing the 7/16". These were a cheap Taiwan set sold by K-Mart and before they bought Sears. They were my Dad's so they have sentimental value to me or I wouldn't bother. I am just curious of anyone has one of these they want to part with? They are slim, smooth chrome like much more expensive wrenches. The part number is 77204. Benchtop. Not to be confused with Benchmark or Benchmade.
