Keith, that is the first Fuji holder i have seen for the smaller film. B&H, Calumet, or Freestyle don't list it as far as I can find. I was left to guess that Fuji simply made film for Polaroid's holder.
Bob, with either holder, your camera will need a Graflok type back to hold it. I have managed to fit the Polaroid 405 holder under the GG frame on a Toyo camera, but it won't fit under the frame of my Crown Graphic. It will fit both using the Graflok slides.
