Hey all, I just got a Retina IIa from a Craigslist poster. The camera seems to be in perfect working shape. The rangefinder seems accurate, the shutter and aperture work fine as well. The exposure counter doesn't work, and there is some dust in the lens (to be expected on both accounts). I want to use this camera, not just keep it on a shelf. So, I want to get it serviced to make sure it's in working order. I've called a few camera shops in my area and they won't CLA because there are no parts available. I have no idea what all is involved in a CLA, so I don't know if it's something I should risk doing myself, or if there is anyone out there that will still CLA these older rangefinders. Please let me know if you have any advice for me. Thanks!
