Shure Unidyne 515SB disassembly?

[Zouto]

Hi,
a friend just brought his trusty but somehow broken Shure Unidyne 515SB microphone.

There are some intermissions of signal, probably some broken wires or corroded switch connectors. The XLR 3-pin plug is ok.
I'm not quite sure how to disassemble it correctly.
Any help much appreciated

On most Shure mikes, the top capsule section unscrews from the main body.

Thanks a lot, it was also a bit corroded but with a little patience it came loose.
So I can resolder all the connections.
