Roger and Rudy,
Thanks for the additional information. I have seen some Dutch-style barns that exhibit what appears to be a mix & match, square rule with diminished haunch and scribe with a square housing. Unfortunately we do not have any documented pre Rev War Dutch-style barns in the western end of the Mohawk. Most of the Dutch-style barns we have are all post war replacement barns ranging from the middle 1780's up until the middle 1850's.
Every little bit helps.
