Hunter made two versions of the Fulton. They are identical externally but the "Fulton Special" has a rotary lock up like the L C Smith and Fox. The other has a wedge that slides into the barrel extension. The one with the rotary lock up brings a premium but they are fairly uncommon and I don't know how much the premium is.
