This is a 4-shaft counterbalance Gallinger weaving loom which I used during a week-long weaving school at The Mannings in Pennsylvania. It's quite old, very sturdy and quite fun weaving with. During the week, I worked on and finished three towels with this loom. These looms are no longer in production.
