The vertical alignment in my Graflex Rangefinder on my Crown Graphic is slightly off. I found what appears to be a service manual for the rangefinder: http://www.southbristolviews.com/pic...TRFService.pdf but it doesn't appear to differentiate between horizontal/vertical adjustments and I didn't want to accidentally make things worse as the horizontal alignment appears fine. Is this an easy adjustment to make? If so does anyone have a link to the procedure or a list of steps to take?

Thanks a lot!
