We have not cleaned these pulls. Someone, at some time, started to clean this set and, thus, one pull shows some bright brass. The cast brass back plates could all be cleaned to be a very shiny brass. We chose to leave the pulls as is with the dark patina—then if the customer chooses to clean the set, they can do so. The bails are steel. Each pull measures 2 3/4 inches across and 1 3/8 inches vertically. With the bail, the overall vertical measurement is 2 inches. This set is from the Victorian era. They could be pre-1900 or very early 1900. Screws are included.
