NH, as I reconsider my proposal I pulled out Timber Framing #81 and browsed on the article The English Barn in America, I found the last section The Foundation to be helpful in that it pointed out how the sills were laid. "the sills were placed, leveled and squared. Than the gaps in the wall were filled with thin shim stones" This does leave us to question what the level reference was, I am guessing it is the top of the sills. Sobons sills were sawn but that doesn't mean they were true. The difference was made up with the "shim stones". Still questioning if the original, and still standing structure had reduction/gains on the sills? Tim
