how remove lens off Durst SIRIOTUB panel - back like key for 'the book of the dead'

I bought an 80mm 5.6 Schneider Componon to breathe life into an old Durst M605 enlarger.....ok....so I wanan take out the 50mm Schneider Componar-C 3.5 lens currently attached to the SIRIOTUB lens panel.....HOW DO I DO IT....nothing seems to budge....doesnt look like it unscrews....the 80mm screws into something judging by the thread.....HELP!

It should just screw into the lens board, but sometimes there's an adapter to fit a Componon into a 39mm board. Sounds like the threads are binding.

It could be just a bit of corrosion on the threads. CAREFULLY place some penetrating oil around the threads of the lensboard, and let set a few hours.
