Seller: number-one (371) 100%, Location: Los Angeles, California, Ships to: US, Item: 172331599221 This is a very nice wind-up doorbell from the late 1800's. The bell is actuated by pressing the button, similar to a modern electric doorbell. The bell is rewound by turning the bell to the right. The bell will ring for about 50 two second rings before it needs to be rewound. Wind-up bells are very practical since most users are familiar with a push button to ring a bell. In addition they are very easy to install with minimal damage to the door, or wall where they are installed. The outside of the door only requires 3 small screws or tacks to hold the button plate and a 1/8" inch hole for the rod. This bell is made of brass/bronze and the back plate is made of iron. The bell is 3 1/2 inches in diameter and the bronze button ring is about 2 1/2 inches in diameter. The 3 1/2 inch long rod is made of hardened steel which would need to be cut to fit the door. The bell could also be mounted through the wall by using a longer rod. The bell is in excellent mechanical condition. The plating on the bell is all intact and shines like new. The bell base has two small blemishes that are barely noticeable when mounted. Overall the bell is in unusually good condition for a doorbell over 100 year old.
