This is of course not so much a build as a rebuild: the boards are rescued from the GWR project, the gallows are the 12" wide set that were last used on Rhiw and the facia boards ditto. This meant that is was just a case of measuring and drilling new bolt holes for these at the appropriate spots.
I still need a name for this and indeed a more positive location. Suggestions on a five pound note please to the usual address.
With reference to the comments in the post below, I feel that this will explain. Not the classic pose, but close.
