Aperture blades on a Bauer 88L

Hi,

I have a Bauer 88L (standard 8) camera, and looking into the lens I found the diaphragm to have a weird shape (I apologise for the image quality) :SShyFPN.jpg

I have seen super 8 cameras with two blades apertures shaped like sickles, but this looks different. Is it broken ? If not, have you seen any other camera with a similar design ?

Sorry if i'ts a newbie question, I'm new to this. Also, there is a switch saying "-2° B", and I can't figure out what it does.

Thanks in advance !

There's nothing unusual about the stop shapes- it's just to ensure that the effective aperture size is always correct when the "sickle" moves across.

These odd protrusions are responsible for the weird lens flare patterns you sometimes see on Super-8.
