I believe this is an old farrier box, used for storing and carrying tools for shoeing horses, and certainly it has done a lot of work, with these beautiful iron corner reinforcements added long ago. Hand-forged iron nails, original red paint, and a leather strap that once would have adjusted but was fixed in place at some point along the way. Very sturdy and useful still as a carrying box for tools or whatever, but also just a gorgeous object.

13 3/4" w x 7 3/4" d x 6 1/8" t, not including strap. There is a split across the bottom, but it remains very sturdy and stable and good for housing/carrying things of substantial weight.
