Here's a nice Toyo roll film slider with a Horseman 120 8 exposure 6X9 film back. Both working perfectly and showing very little use. This version replaces the ground glass back on Toyo view and field cameras. It will not mount on other brands. Compared to the Toyo version for Graflok International backs, this one produces less extension and permits the use of shorter lenses. However, these devices are not intended for wide-angle work in any case. On a Toyo 45G with standard bellows a 75mm lens in a recessed board can just focus at infinity. Anything shorter will require a bag bellows. This rig works great for the job it was intended, figures and portraits with lenses longer than 100mm.
