Thanks for the info.
As a member of the Friends of Ohio Barns, I was alerted of the need to label the frame pieces by bent and position. Nailed on aluminum plates with laser printed labels (the laser printer carbon toner shouldn't fade like inkjet ink might). Didn't do the rafters, and may have missed a few wind braces, but being turn of the century sawn, many pieces are probably interchangeable.
David Now, the contractor I hired to do the crane work dismantling the frame, had worked on the reconstruction of the Muhlhauser Barn for the village of West Chester, Ohio. He said this barn had some similarities to that one.
