Up for or sale 3 vintage cast iron covers, not matching.  They are from an estate of an antique dealer and I am not sure it they are floor register covers or for a vintage stove.  You be the judge!  Some damage on the little nubs on the bottom.  They will be shipped FedEx ground, they are heavy, and will only ship to the lower 48 states.  No shipping to Alaska or Hawaii or addresses outside the USA.
