Came back and found I had a flat tyre.
Not had one since we bought the car.
Got the spare out, jacked it up, got the wheel wrench and found it didn't fit!
Tried ringing for help but we were so far up and away from civilization we got no signal.
We eventually found a lone lady camping next to her C1!
Her wrench fitted perfectly.
Wheel changed.
I looked at the wrench she had, it said SG9 on it, ours said Ford!
So, came home and sourced a correct one https://www.ebay.co.uk/itm/331600887694 ... EBIDX%3AIT
Might be worth checking yours if you've never looked
