This picture proved particularly useful as it clearly shows how the posts are separate to the panels, the details of the posts and how it fits together.
I figured that I could quickly put together a couple of panels from a leftover piece of the Parkside Dundas fencing used on both 'Shifting Sands' and in cut-down form on the diorama 'The Path to...'. The length used here was destined for that project but had unfortunately snapped during construction.
I have assembled one panel with two legs, the other with one. To aid holding during painting and to strengthen the future central joint 0.5mm wire has been inserted in the top and bottom rails - so at this stage it cannot be fully assembled as the wires are over-length!
