Seller: number-one (399) 100%, Location: Los Angeles, California, Ships to: US & many other countries, Item: 172415479150 This is a very nice all original lever operated doorbell. There are no markings on the bell but is probably from around 1880. Similar bells are from the 1870's and this is an improved bell. The bell is, except for the center nut, made entirely of iron. The lever and plate are made of brass. The bell is 4" in diameter which is just the right size for most houses. The lever plate is about 1 3/4" by 4 1/4". The bell should fit a door at least 2" thick. The Bell has a bronze finish that is probably lacquered. It is in excellent condition for a bell over 120 years old. The lever and plate also have a bronze finish. The bell has a complex mechanism that produces a ring as the lever is pulled and a second ring as it is released. Unlike a bronze bell the iron bell gives a nice sharp higher pitched sound. This is a high quality bell in very good original condition.
