Question
Hello! After buying a number of antique clocks over the past year, mainly very dirty or needing oiling. I have finally gotten the nerve to take some of the movements apart.  I am working on an en welch/sessions half hour bell and hour strike mantel clock.
My questions are concerning the striking for the hour. I am not sure if I understand which lever or part stops the strike after it counts the hours.
The strike will not stop.
I do not understand if the lever that is off the count wheel is the main stop or if it is another lever that should drop into another wheel.  I have the Clock Repairs Handbook, by Laurie Penman, and this chapter is not helping.
Any suggestions, or what books to buy? I am working only on late 19th and early 20th century pendulum clocks.
Also concerning the wire that wraps around the half hour bell/hour gong and other chiming shafts, do you have any suggestions on size/type of wire?
Thank you!

lever dropping into the deep shut-off notch in the count wheel is connected to the internal shaft that DOES have the lever on it that does shut off of the striking. it either drops into an internal cam notch on the shaft two shafts away from the fly or has a wire arm with a little hook on it that catches a pin sticking out of the side of the gear that drives the "fly" or governor itself.
