Me Lady just discovered this lens amongst some darkroom gear that was her late fathers. It's mounted on a Graflex lens board. I would like to play with it as a possible portrait lens for 5X7. I read someone had mounted theirs into an Alphax #4 shutter. Anyone have any experience with this lens? I would like to know if it will be worth the expense / trouble of locating a shutter, and if there are any other shutter options for it.
