Considering a DIY CLA on a Canonet QL17 GIII?
Yesterday Mark Hama was kind enough to send me this image of my QL17 as it currently sits on his workbench. If you look closely you can make out my name and the camera's serial number on white tape on the lens cap in the upper middle. And this appears to be only a partially disassembled lens assembly. That piece in the upper right below the body looks like it could easily be broken down further. Yikes.
What a testament to the golden age of mechanical engineering.
After seeing this I don't think I'll ever be tempted to pull one apart on my own - no matter how many well-intentioned posts I read that say it's a "piece of cake" if you're careful and don't misplace any parts.
