This stunning brass bell can be mounted to a wall using a nail - it has a hole in its back plate for this purpose.
I'm not exactly what purpose that chain on the back serves, but it looks real nice.
It's possibly a 1970s/80s replica of an antique monastery bell, and could be repurposed as a dinner bell or door bell. It would also make great wall decor in general.
Measures 5" in height x 3-1/2 in length x 3 in width.
