TLC Camera Repair is in High Point, NC. I haven’t used them but might one day. I share this URL to make a point. Knowing who repairs old cameras still is important!
I’m learning with old cameras and lenses you have to CLA. That’s Clean Lubricate, and Adjust. Sometimes you can buy a old camera that will take good pictures without a CLA first. But at some point they’ll need it. Just like old cars.
