Unfortunately, it is just an educated guess.
With each of the manuscript images I am including a drawdown of the pattern and a brief description of the pattern and weave structure.
I obtained permission from Winterthur Library to post images of the Jacob Biesecker manuscript and from the Free Library of Philadelphia to post images of the Peter Diller manuscript. Digital copies of both of the manuscripts can be obtained by clicking on the link for the weaver’s page. Yesterday I added images from the David Bender manuscript per the Bartlett Library and Archives of the Museum of International Folk Art. The manuscript has not been digitized yet, but you can obtain individual images by telephoning the Library at 505-476-1210 or emailing at Bartlett.Library@state.nm.us. If more interest is shown, hopefully the manuscript will become available sooner. See below for an image from each manuscript.
Several manuscripts have been published in book format. I also recommend you check out the Early American Weaving Books and Manuscript Study Group for the Complex Weavers at http://www.complex-weavers.org/study-group/early-weaving-books-and-manuscripts/. You can obtain photocopies of many manuscripts from the group.
