I went to Grantham NH and worked with a friend taking apart a very old post and beam house. He will move it to S> Randolph, Vt. We took out all windows, doors, floors and bagged 70 contractor bags with the blown in cellulose that was in the walls and ceiling. The man that lived there until 5 years ago was 92 when he died.
The beams in the house are supposed to be chestnut. Some of the boards used for the wainscotting in the parlor were 26 " wide! Others in the floors were from 10" to 22" wide, pine.
Quite a well made house. Trim was put in very carefully and tightly.
