European antique brass bar service bell is a classic calling device at the front desk of hotels and restaurants in the mid-20th century. It is cast in one piece of brass and has a concentric turning spiral decoration on the top. It has a built-in mechanical spring percussion structure. When pressed, it can emit a clear and loud bell sound, and the mechanical function is intact. The overall body of the bell is coated with warm paste, the brass color is natural, and there is no obvious bump damage.
