Picked this up a while back, It is about a 4-5 inch movement. Took it down this evening and ran it through the sonic cleaner twice after removing as much crud as I could by hand. It is now soaking in light oil. Have to get some murphy's and more ammonia tomorrow to make a cleaning solution . Not sure what I am going to do with it as yet , Have been looking for something to mount it in but have not ran across anything yet. Forgot to add , this movement actually has a hairspring escapement which is why it caught my eye. All my other clocks are pendulum escapement.
