This is an Antique Ansonia Open escapement clock with original movement. There appears to be a back cover that is missing. It comes with key and pendulum that appear to be original. It is a beautiful 8 day clock that runs and chimes well (hour and half hour). Dimensions are 13" tall, 11" wide, 6 1/4" deep with a dial diameter of 5". Though the movement is running well and has been recently serviced, the impact of shipping can sometimes result in the need for adjustment or service.
