This is fascinating, those cameras are absolutely stunning. I love the ones from The Big Sleep and Rear Window!
Thanks, Antoine. Most were obtained from various auctions. I've learned to see beneath the dirt and grime and many times I'm able to get cameras in great condition for a good price. I've become pretty good at refurbishing them, mostly disassembling, cleaning, and bringing old shutters back to life, but many of my more complicated Zeiss Ikontas were sent to a pro for CLA (clean, lubricate, and adjust). I do take care not to do too much restoration - no repainting or refinishing the mahogany on the plate cameras. Finding a close-to-mint camera is the key, then just enough care to bring it back to life. It's pretty amazing to find 70-100 year-old cameras still in operating condition.
