I am working on an old German AMUF tall case clock and found this T-1 sprocket. It’s a good example of what happens when a bushing is misplaced. Someone bushed the plates on this T-1 arbor and the one nearest the wheel was not centered and this is the results. It evidently ran for years with the T-1 too far away from the T-2 pinion and all the teeth are deformed. This is why depthing is so important.
