Measures 4-3/8" tall and weighs 3oz. The spring at the top appears to be messed up. Sold as is for parts or repair. I've recently acquired a portion of an estate from a local clock maker who has passed away. Though i don't know too much about these items I am trying my best to represent them accurately. So if I've missed any information or you'd like more pictures or details don't hesitate to ask! I absolutely combine shipping wherever possible if you're interested in multiple items!
