Mike - A little web snooping on the first "591" wrench came up with a few similar wrenches being offered on ebay by different sellers in different parts of the country. Pics below from those ads were described as "Vintage Number 591 Hex Wrench Tractor or Steam Engine 6 Sided Tool" and "Antique Hex Wrench 591 Hit Or Miss / Tractor / Steam Engine 1 1/4" so that may be good info on that wrench. The other one may be for a similar piece of vintage/antique equipment. Looks very much like it may have been hand forged.
