It appears that there are two ways to mount the Fujinon 400mmm T lens to a mounting board. Looking at pictures on epay, I see some boards mounted immediately to the rear of the Copal shutter. Others use a Horseman(?) board that mounts on the rear of the lens itself. Why are these mountings different?
How would I remove the Horseman(?) board to use a more convectional mounting at the rear of the shutter?
I have made a couple of photos to explain my problem in more detail. The question I have is how do I remove the lensboard/tail piece that the lens in mounted on? I don't want to force anything since it is not obvious to me how the lensboad/tail piece actually detaches from the lens. Please help.

Thanks for the pictures. I was pretty sure that was how the board should be mounted. My question is more basic. If you note the lens board in my photos is mounted on the rear edge of the lens. The board itself is rigidly attached to a cylinder that extends to the Copal shutter. My question is "How do I get that board off?" I don't want to damage anything in the process. The lensboard/cylinder will rotate but it does no unscrew from the lens. So I am still confused.
Thanks for the suggestions. The top hat was screwed on very tightly and had very little clearance at the back. There was only about 1/16 of an inch clearance to hold onto when trying to unscrew the rear lens.
I finally did get the rear lens to unscrew. I was able to attach a conventional Copal 1 lens board. This was a real learning experience.
