DeColorado: You certainly will not have any problems with the lens on this one. But ... after all these years make certain to determine if what APPEARS to be in focus (VF alignment) actually IS in focus (actual negative: film plane).
For too many people, the VF is the ONLY test given and, oftentimes, a wrong conclusion is made about lens resolution. You probably already cleaned the VF area when you removed the top. But this extra test is essential if you wish to truly enjoy its glories. Japan was ignorant of how to make a bad rangefinder camera. - David Lyga
