three pair of antique curtain rod mounting brackets

Lot of three pair (six single) antique, Victorian vintage, cast iron curtain rod window mounting brackets. They measure about 2 1/4" long, 1 5/8" high and about 1/4" thick. The mounting holes are about 1" center-to-center and the pockets are about 1/2" across the top and 1/2" deep. These have a patina of age and light rust.
