Does anone know how to disassemble this lens, esp the front element?  My copy has fungus and I would like to clean it.

I have managed to remove the back group easily, but how do I remove the front elements?

Managed to remove the name plate, the first front element drops out, but I can go no further. There are no retaining rings to remove the 2nd element. I need to get to the back of the 2nd and 3rd element

There are 4 screws on the side of the body next to the aperture ring, and another 4 screws on the aperture ring also. Should I unscrew the 4 screws that are on the body?
