Hello, Here is a weight-operated wall clock that has an attachment for ringing bells or operating some other device. The brass wheel has markings for the hours (1 to 24), and holes where pins can be inserted to close a contact that is connected to wires that go out the top of the case. The movement plates are stamped with the number 2, but there are no other markings that I can see. The weight shown in the picture is not original and is too large in diameter, as it will interfere with the pendulum when it gets toward the bottom of the case. It's an eight day clock and the case is approx. 34" x 13" . Has anyone here seen one of these and know who the maker might be? Thanks, Pat L.
