These pressed metal pulls are of the Waterfall era (1930s-1940s). They were probably on a bedroom set with its curves and rounded edges. The curved handles compliment the Waterfall motif.
Each handle is 5 1/2 inches long and 1 3/4 inches wide. The hole centers are 4 inches. For the screw, which is inserted from the back of the drawer, the metal is folded over in the back of the pull and threaded for the screw.
Even though, the Waterfall era married into the Art Deco period, these pulls resemble more the Victorian flavor. Very unique.
