I have this old wrench with the Ford logo on it. It is actually metric, and I have always wondered what it was for. As far as I know he never owned a Ford, he had a Whippet as a first car and other non Ford vehicles later in life. He never drove, grandma did all the driving.
It was in the old tool box from my grandfather. He knew as much about cars as I know about ancient French poetry.
The wrench is just a wall hangar, next to my timing light, brace and hand drill.
