Hello, I have a 16s grade 304 model #7 Illinois pocket watch. My best guess for a clutch lever spring is #1532 BUT I would like your opinion before I spend too much time making a new one. As you can see the original has broke and it looks like it had stretched out the one side, could not find any pieces in the watch either. The reference book I am using is the illustrated manual of American Watch Movements by the E & J Swigart Co. Thanks and have a fantastic day , William
