As I said, it's easy when you know the answer! I just worked away from Ham Street, staying close to the Military Canal. Went past it twice, third time I went down Marsh Road.
Sorry about delay, been refurbing the loading port of my 40odd year old BSA Airsporter S rifle. It now has a new detent spring and ball, only a couple of mm diameter. That was fun to find when it inevitably shot across the workshop. Done now, calm has returned and I'm ready for the next rat that comes after the bird feeders. The Airsporter packs quite a punch, my modern air rifle is less certain of a kill, weaker (legal?) spring but nicer to shoot. I hate rats
Next one is a disused water tower, so no surprise its on a hill! But which one? GSV is very similar to this view, close to a road.
