Calling Gordon

It's possible that the uprights may have been planted with the tenons pre-cut, then measurements taken and the mortices cut in the lintel to suit.

2 things.
1/ Some of the lintels have holes on both sides so they screwed up at least once.
2/ The stumpy stone is too small to have had a lintel so there must have been a gap in the SW. therefore there was never a complete circle of lintels.
