The rear element has some minor "haze" and I tried to remove to try to clean it up. Reasonable force to unscrew was unsuccessful. It's a Sinar select lens factory mounted on a Sinar board purchased new, and I really enjoy its results. Had CLA by Flutot, Carol asked if she should try to remove it and I said no thanks; probably should have let her try. Anyone try to do this?
I have the same problem.

Ok Jon, I'll give it a try since you imply that the rear element is actually threaded into the shutter and it's just a matter of "breaking" the friction loose (rather than breaking the element).
I see, you cannot unscrew the rear from the shutter, I can do that, but my problem is the inner surfaces.
Good luck.
Randy, what do you mean by "the inner surfaces"? Internal lens surfaces that are "hazy"?
Or perhaps just use a rubber jar opener to grip?

There are air gaps inside the rear element.

That may be fungus. Exposure to a good dose of UV light will probably kill it.
