Yea, I like them jumble sales. Today I came home with this:

It is an old dynamic microphone from Sennheiser. Can't find any information about it anywhere, so I don't know how old it is - Do you know? Since the plug is different from the regular mic-plug, I had to open the plug and twist it a little to make my own plug, so it fitted in the mixer. I succeeded in getting some sound through it, but it resulted in some serious crackling sounds from the mic, so I decided to take it back out. Well, that was today's catch.
