Posting from my phone. I got it free from a customer, glass is sharp just needed a cleanint. Light seals are GONE. The shutter ring and the aperture ring are loose and after some playing around I can get it to change aperture. Shutter works and sounds accurate and the light meter is on par with my Nikkormat. Where do I get seals and how do I fix the lens? Its a 1:2 45mm rokkor.
