This loom has one shaft with a fixed heddle "bar". There are two sheds, one "at rest" and one where the heddle shaft is raised by that crank in the front. There is also a reed. This is a small table loom. I did not see any maker's marks on it, but as it was at a demo in NJ, I didn't have a chance to inspect it carefully.
Has anyone ever seen a loom like this or know anything about this kind of loom?
