1956 Belair clock solenoid issue

Please see the photo to better understand the question. Basically, my clock is good to run once until the spring winds down, because the point stays open. Assuming the points are closed (yellow arrow, blue arrow, and red arrow pieces are touching) and I apply the electricity, the pivot arm (yellow arrow) pushes the point (blue arrow) open where it will stay there forever unless I close it. Despite the extension spring, the point (blue arrow) has only two modes: resting against the pivot arm (yellow arrow) or wide open as shown in the picture. I think I could be missing a piece where the green arrows are located. If you think you can help me save this original clock, I would appreciate any input
