I understand it's quite difficult to understand, I'll add a couple of pictures here now.
The thing is that the top cap technically is there but when I remove the bolt, the "cap" won't come out what so ever so I can't even see if I have a star nut there or not. The cosmetic cap that would make it flush with the stem has popped off though.



The headset isn't ovalized either, it measures exactly 45 mm from every single angle measured from the black headset cup, 360 degrees so the diameter is exactly 45 mm.

You can see that the headset cap has some kind of a place where the screw goes into but I can't understand what kind of a mechanism it is because it doesn't look like a star nut to me. MORE PICS:
