This is a nice set of 9 original cast iron with brass ornamentation Eastlake style window sash locks and 5 accompanying original catches.  4 of the locks will require a catch.  These are circa 1880s  All seem to work well and lock tightly. We have not lubricated or cleaned in any way. Base plate and catch plate measure approx 2" in length, 1 1/4" wide and the circular base portion is 1" in diameter. Height of item is also about 1". All  have minimal surface, corner and edge wear and light oxidation. One of them is quite oxidized and tarnished. One has some trace areas of white paint where it met the window. Please study photos carefully and eMail with any question. These items would make a great addition to any collection !
