I spy "18"

No Neil 

You are looking at a lot of it. 

Not concrete John, but you are in the right area of thought 

I feel that rope being brought out of storage  

Vince, I was looking for English spelling version Cornish Granite, but you have it. The other one is Portland Stone. It covers the metal work on the towers.

Well done, over to you  

  I realise that but you know I fly the Flag when I can.

  It did throw me a bit when you said there is a county connection cos to some Cornwall is not a county of England but a duchy in it's own right- better stop now as I do not ant to start any wars. I did enough of that when I sent a get well card to my father when he was in Derriford in Plymouth and addressed it to the hospital, Plymouth devon Near Kernow - Dad said it was the battle of the Tamar that day between nurses of each side.

              Better have a look now.
