First, Racer....the phillips screws show no sign of ever being removed. I always see, even the very best repair shops will put a mark in the screws, most often the slotted too. I am stupidly careful to never mark a screw, so I take note of what type of ape has worked on the motor before me. As I work on these I have just one phillips that I use that fits these screws perfectly, no one else uses my tools, ever. This looks like a "time capsule" 9.5 to me. OP, you are probably right, it has never had a puller installed before. I think that in 1973, this style coil was just beginning to be introduced. They can crack too, but not as severe as the older style with the very common coating which becomes brittle and shrinks, opening huge cracks and falling apart. I have a large box of them. When I was trained at OMC, the ground wires were to be installed in this position to help stop them from spinning as the slotted screw is tightened. RARELY do I see a previous repair set up with the ground wire positioned as shown here. The guy that assembled this stator was certainly a real pro.
