A heavy 1920's-30's brass Westminster chimes mantle clock movement. I have checked the three springs, all are okay and have let them down as a precaution. The suspension arm swings freely. As you can see from the pics, the movement is complete save for a pendulum but would need a really good clean and service. 

There is no maker's name but the number '3851' is stamped into the bottom of the backplate. Its rather solid and well made tipping the scales at 1.6kg and is approx 5.5" across. I am selling it as 'spares and repair, so a great project for someone.
