Found the board. Sorry for the crummy picture. Also it's soldered in place so I can't immediately see the bottom.
I guess mine are different (they have the two little extended nubs on top where as your don't extend out). Also the top on mine is flat where yours has a slight grade to it.
This is what the guy said my switches were. It was on another site so I'm not sure who he is but I think he's probably a DT user.
The switches are probably stock M61-0100. M7 is German and looks quite different.
Btw how many M7 switches were you looking for?
