It was 50 years ago Stanley, all our local natural watercourses had plenty of fauna then. All feeding the Ribble of course. Last year was the first time for years that I have seen any fish at all in the becks and then only down by the bridge in Victory Park, some rather small stickleback fry. The becks are clean enough but seem to be devoid of the fish they used to sustain in quantity.
Your mystery object looks like a 7" lump of brass bar, but I know there will be more of a story than that.
