Wooden Mantle Clock

 This clock still works. It is a wind up clock and chimes on the hour and half hour. One chime for each hour and then only one chime for the half hour. It is a very simple clock made of wood. It has a glass door which you open to wind it.  I looked all over it today and could not find a mark of any kind. Hopefully someone will know about when it was made and how much it might be worth. It does have a hanger on it so it could be hung on the wall. I believe you can see it on the top of the clock in the back in one of the pictures. Any help will be greatly appreciated.
