For your consideration, I have a Vintage Kennedy KIts 1018 Cantilever Metal Tool Box/Tackle Box.  This is in very good condition.  The top folds out easily and shelfs are in great condition with little rust.  It measures 10" x 18" and is 12-3/4" tall (not counting the handle).  This doesn't appear to have been used a lot.  This comes from a smoke free home.  I will be listing several vintage items so check out my other listings as I will combine shipping on multiple sales.
