Which peg hole was use in that brace?

How about a close up picture of these snap lines?

What was the foundation like, as Don inquired, and the floor system, did it have a drive bay in the center and what was the flooring like on either side? Was it original of mucked together? Other details on the flooring? Bare ground?

What is the height of the post? Can a man walk between the upper Tie and lower cross beam? Was there any flooring on this second level? And if so did it extend across the drive/center bay, at any point?

Did you find any left over straw, tobacco leaves, animal dung, or other signs which could possible point to the former use of this barn?
