NF,
While I am not a framer or a carpenter, just a student of old buildings, I have some information that might be of interest regarding plank construction.
My son bought a house that was built in 1820 and the main core of the house is plank construction. The planks exhibit up and down frame saw marks, probably single bladed by the width of the curf.
It is a lightly framed house. I do not know if he has any photos or not. Probably no as he was more interested in getting the interior walls back up.
If I can dig up anymore on it I will post it up to the sie.
