Thanks Colin; I will . I’ve never seen it in use though, but the idea came from looking at the bonnet of a 12 cylinder Bentley! In August, I spent some considerable time with David at Trident in Gateshead, trying to think a solution to an adequate hatch fixing, to no avail. Then saw a historic vehicle rally; took a photo and weeks later the idea evolved with an engineering friend. It will be a great help if a kit is already available as its this one hurdle that has held me back finishing my restoration.
