Subject: [Leica] Disassemble a DR-Summicron

Hi, LUGgers:

    I recently purchased a DR-Summicron from Ebay. After I got the item,
I found that the rear element was severely scratched and the coating is
nearly all gone. The worse thing is some of internal elements are fogged.
Yeah, I can send it to Sherry and wish there will be some improvement --
but I cannot wait for 4 weeks before it's back to my hand. Anybody here
has some hand-on experience on disassembling a DR? I am a science grad 
student so the tools and chemicals are not a problem to me. I just took
a look on the rear element in the optical part and found that it appears
to be fixed by a black ring that has two notchs on each sides. Shall I
rotate the ring or just pull it out?
