Having purchased a bum Kodak Retina IIc last week, I want to fix the cocking rack on the camera myself since I'm pretty sure I can. I want to clean and lubricate the internal workings while I'm in there doing that. At the same time, I want to disassemble the shutter enough to clean and relube it as well. Having never actually taken the time to relubricate these old cameras, I have no idea what oils to use. What are some suggestions for brands, weights, types? I assume the oil for the wind gears would be thicker than whatever will lubricate the shutter mechanism. Thanks for any info!
