I have a tandem-wind New Haven balance wheel movement, but do not understand why it is designed as it is. The "front" looks fairly typical, except there are no winding arbors. The minute arbor extends out the "back", but has no method to connect anything to the long shaft (short of a set screw collar). There is an "hour" cannon on the back. The "back" also has the winding arbors.
How was this clock used? What connects to these features on the "back"? In what kind of case would this movement be found?
Many thanks for any help with this!
