Vintage Small Red Metal Aluminum Box with Shelves and a Door. It has a Hook on the Top.  The inside is reflective tho scratched.  Not sure what this box would have been used for or maybe it was homemade in the guy's shop.  He had stored some of his rock and fossil collection in it.  It measures 5" by 7" and is about 2 1/2" deep.  It does have some scratches - See pictures for best assessment of condition.  Please ask questions!
