I was doing some work on my rally car and had to remove the water and oil coolant lines to the turbo. Very tight quarters and couldn't get any sort of wrench on the water line without partially disassembling the turbo. So I went DEEP into the recesses of my tool chest and found an old open-end wrench stamped 'Ford'. It's very thin and has sort of tapered openings. I got it from my Grandpa 30 years ago and forgot about it. Worked perfect and I now keep it in the car's tool kit. Turns out it's a 1917 Ford Model T wrench
My Grandpa was a Ford mechanic.
