Open 617 Camera V8 Lens Cone for 90mm Fujinon SWD f5.6

@MortenKolve_243546's Lens cone for the Fujinon SWD 90mm f5.6. A mock-up of the rear element and the needed lens board are included.

I took @MortenKolve_243546 lens cone and modified it for the Fujinon SWD 90mm f5.6 lens. I'm certain it will fit with 3mm to spare. The rear element needs to be inserted first into the cone and rotated into position. Then screw the lens through the lens board.
