Yup it's in County Durham. Handily only 30 mins from our house. Will be having a few weekends up there this year I think. Nice little village.
Mine isn't a figure of 8, rather has a recess that fits snugly into the gutter. It's softish rubber/plastic so won't mark.
I think if you don't mind old school gear keep an eye out for the older awnings (70's / 80's). eBay and vintage sales.
I doubt the plastic 8 strips will damage the paint Ken. They've never hurt mine even when it was as freshly painted as yours.
