Just as you think, the outer ring of the lens unscrews and the cap of the center. You have to make a tool in both cases. The center has a second double ended screw pivot. I doubt they were gassed as that didn't come for years after so a complete strip and clean will help. I do optics for a local curio shop, they aren't too hard...40TPI screws and such...
