Seller: number-one (372) 100%, Location: Los Angeles, California, Ships to: US, Item: 172401811887 A very nice original iron and Brass/Bronze lever operated doorbell. The bell and lever were made by Sargent and the bell has patent dates of 1872 and 1878. Sargent made one of the best lever type bells. They are very well made and produce a consistent loud ring as the lever is pulled. They probably could have given a life time warranty without a lot of risk. The Lever was also made by Sargent and is appropriate for this type of bell. The Bell and Lever are 100% original. It is very rare to find a Bell that has not been painted, repaired or is cracked. The Bell is made of Brass/Bronze specifically made for Bells. The back plate is made of Iron. The Lever and Plate are also made of Brass. The Bell back plate has been refinished with the same type of varnish, not paint, originally used. The Bell is 5" in diameter and the mounting lugs add another inch. The Lever Plate is about 2 3/5" by 5 inches. The Bell should fit a door up to 2 1/4" thick. The bell and handle are in very good condition with almost no noticeable wear. This is as good as it gets for a lever type bell. The brass lever is is also one of the nicest. As opposed to a reproduction that will decrease in value this bell will only increase in value. If you are looking for one of the best, you may want to consider this Bell/Lever combination.
