I had a stroll up Carnedd Daffydd last weekend, to have a look for the missing Cessna engine block amongst other things.
No luck with the Cessna, but came across this bit a long way from any sites I have been to before. Despite the report from a dog walker that he had seen the engine block at a new site, I'm wondering if that Cessna engine block is decorating some magpie's garage. We had a good look all round where it used to be, and on the obvious lines someone might have rolled /dragged it down.
Anyway, the bit pictured looks like a bit of armour plate shaped to fit the back of a seat, (head end down in the pic) with some skinning attached. Nothing else around it, and I haven't seen it reported elsewhere.
