I have a GB (that's on the face) weight driven clock, and the movement is marked Junghans P64. Anyway, on the left side is a lever that operates the strike lever, and that lever is missing a flat spring. I need to know what that flat spring looks like and how it interacts with the steel multi-faceted part that's between the plates. A photo of the location and the multi-sided part is attached. A flat spring came with the movement, but I can't be sure it fits in that location. I looks to be too long.
