Royal 35-M servicing
It's a real basic simple camera: if you took it to a repairman he'd probably just look it funny. So if you want to DIY...
The bezel holding the front lens elements on both the 1.9 and 2.8 simply screws off with your hand. The rear element you'll need a small blade spanner for, and it's holder unscrews from the film chamber.
No need to disassemble the Copal shutter: it will come back to life with careful cleaning.
There's an eccentric that adjusts the rangefinder with the top cover off. That screw on top of the camera is a meter-zeroing screw (it does not unscrew and does not come off). Rangefinder glass cleans with top cover off (don't touch the silvering).
The top cover comes off easily. Only things holding the top cover on are the advance lever (black center button needs a small needle spanner), rewind button (unscrews from shaft) and 2 screws at cover ends. There is a wire between the meter and booster cell contact screw inside cover, don't break this (small nut holds the contact together, but its a pain to reassemble).
The helical is accessible without removing the lens from the top and bottom with the covers off. Can clean most of old gunk this way. Do lightly lube brass gears. Basic and well built camera, easy to CLA.
Using my Royals can say they've been reliable, and most of their Tomioka lenses crisp (only had one that was foggy/off). For metering, match the red pointer with cover closed, green pointer with cover up. Black pointer is for when the booster cell is attached (& cover closed).
One thing though: be careful about the chrome, it's very thin & corrodes easily. Manual suggests wiping off after use. Don't store camera in case if anything (even the weather) is damp (lining will eat the chrome).
