135mm f/2.8 M42 : Teardown and oily diaphragm cleaning

Описание: Hello Friends,
This lens here has seen some action before reaching my hands, the owner, a friend of a friend's girlfriend love this lens and the diaphragm was blocked, took it to some camera shop and they asked a ridiculous amount (100€) just to determine what the issue was. He told me the symptoms and I told him, that's just an oily diaphragm........now give me money.......hahahaha

Anyway, I show you how to fix a very common issue on a very popular vintage lens.
