From behind the shed, I found these when pruning/deforesting.
Cobra Superslots 14x6 ET12 with a PCD of 114.3mm (or pretty damn close!)
Got them for a mate for his pop top bedford rascal but they poked out a little much so he didn't want them. I've given one a quick go with some scotchbrite and it comes up ok, so I'd be hopeful for the rest. They are black on the back side and that is in good nick.
