This is a fine Museum Quality Tiffany Studios Reproduction of their Tripod Oil Bronze Base. This is a large lamp base, standing 33 inches tall on its 11 inch patinated Bronze Base that features bronze beads around the base plate edge.  It features 3 sort of Tiger paws supporting the oil tank on a small pedestal with seashell and leaf sculptures at the head of the supporting arms. The well sculpted Patinated Bronze base has a great look to it with Brown Bronze highlights. Check out the photos. It may well be one of the design hangovers from the oil lamp phase of Tiffany's Lamps.
