Nice to see some comment and query on recent posts; thanks for the interest guys!
Pete M asks about the grass mat. On the bridge, I used the Gaugemaster rough grass, autumn brown (?). It's actual made by Noch and no doubt Gaugemaster are the UK distributors. I will also be using other products to represent ground cover including Greenscene, Noch and Woodland Scenics as well as non purchased items such as soil, tea leaves and dust (!). I expect that the Noch grass mat will be usable in fairly largish patches; it could perhaps be used for a crop field with suitable treatment although not in my case.

No doubt this is barred under various EU legislation; usually the same sort that stops us knowing who our fellow members are and where they live! Don't get me started on that again...
