My "guess" would be that the PO had starter problems, attempted to solve them with a rebuild (part number.....X), and when the symptom came back, fitted the FORD solenoid to increase the voltage to the Bosch solenoid when cranking. If you are unfamiliar with the 911's starter issues, search and read the archives. As the Bosch starter ages, it becomes sensitive to voltage drops and develops an intermittent problem. The 911 has voltage drop problems because of the distance from the key to the starter , the many connections along the way and in the 83SC, the A/C relay in the circuit. The Bosch rebuilds often fail to resolve the problem because the rebuild does not address the problem area. Now that the cores are all over 20 years old, my advice is to put it back the way it was or get a Japanese gear reduction starter. A smart $8 addition is an engine compartment cranking button. The 911 starter is hard to reach in the rain at night and the button will often get you going.

+1. However that Ford starter solenoid is kinda overkill - typically used to switch heavy starter motor current. A regular Bosch-type 25A relay is sufficient.
Here's mine squeezed into the rear tunnel:
