Hello all, 
 
I just purchased a used Biogon 21mm from bhphoto, and the mark for aperture does not line up with the numbers... do any of you know how to fix this? I realize I can simply use a permanent marker to set where the small notch should be, but I'd rather have it properly aligned.
 
Thanks for any suggestions/help!
