Open 6x17 V6 lens cone Graflex Optar 135 f4.7 lens

I've been getting asked questions about this lens cone on reddit and etsy by a few different people, which leads me to believe others would like to give this lens cone a try. I had the FFD marked down some place, but I've misplaced that and will have to confirm it again hence why I'm uploading this file. I will do some testing down the road to get the FFD again :)

I've tossed the fixed focus version and the m65 helicoid version up here.

Note: The fixed focus version will require you to make a hole in the lens cone to fit the little nub that sticks out of the graflex optar on its back side. I generally just attach the lens, jiggle it to mark where the nub sits - be mindful of the orientation of your lens at this point - and then drill a small hole through the lens cone. You'll want to light proof that some how, I generally use felt.

Good luck on your panoramic adventures.
