Konica Auto S2 shutter repair

[jonathanr]

Hi there! I'm Jon, new to the forum--I've finally found myself with a bit more free time to try and am trying to fix an old Konica Auto S2 that looked beautiful but seemed to have its shutter blades flailing freely inside the lens. I'm entirely new to camera repair...

And I've found myself stuck in terms of figuring the next step to take to remove the rear elements/shutter mechanism to get at the leaf shutter blades. I've attached a picture to see the stage I'm stuck at--if anyone can point to the next step to take to get at them?

Thanks!
Jon

Undo the retainer ring on the back, you can see the two notches at 1.00o'clock and 7 o'clock.
