Anyone have photos of a dis-assembled Cooke Knuckler or drawings. I'm baffled.

I have a VERY stuck one and I have the front and rear glasses off already of course. Those are simple enough. But I'm a bit baffled how the middle glass comes out and I don't want to soak and "massage" the stuck barrels with the middle glass still in place. Any help obviously much appreciated. No guesses please.

The barrel is likely thin brass and as such will jam if uneven pressure is applied while trying to unscrew.
Please post so detailed pictures of the barrel at the center element.

This is a more ordinary Series IIB Classic knuckler. Also I am not lately on friendly terms with LFPF so cannot see images there. But thanks!

Well, I guess the answer to my question is . . . no.
