This is a rare maker's marked wrench, antique buggy or machinery type wrenches. It is marked in raised cast lettering "QUAKER CITY IRON WORKS 1329" on the handle section. The wrench has one square box wrench size 1/2", and that socket shaped end is 1" deep. The wrench has some pitting on it, but is not rusty, not damaged, some minor dings, the handle is almost perfectly straight, in good condition overall. Although the name is on this wrench, we don't know what company this was as no location is given, but most likely from the New England states area, and my guess would be Philadelphia PA.. Unique!
