OK, if that first barn was indeed scribed, what was all the pencil about and where were the marriage marks? I see what you mean on that odd housing. I remember that post w/ the housing was 9 x 9, while the post on the opposite was 7 1/2...
Orientation... you mean referencing, right? The rooflines of both barns share an east/west axis. According to my notes and recordings, referencing on the first barn faced east (looking toward the rear of the barn). It was just the opposite on the second one (west).
I'm not quite sure what you mean about the replaced sides: the first had the sawn posts on the north side. The north side of the second barn faced the road. That 2nd barn needs help on both north and south. The owner replaced the sheathing on the south side.
