I managed to loose the screws on the focus collar without heating/cooling, using the better screwdriver, the tip was filed on grindstone, to be just right fit for the slot in the grab screw.. there was the click sound when the glue cracked inside the thread.
However, the back screws (4x philips, a gateway to mirror, I hope) I left for now, the fungus cleaning is the first task.
The next problem is dismantling the front end .. despite the grab screws are out, the barrel is tightly screwed in.. hopefully not glued.
The reason I am trying this first is because I suspect there may be grab screws for the front lens retaining screw ring (I had this when dismantling MTO1000A).
