I've had good luck so far repairing CL, so before giving your dead CL to a kid as a toy or something, send me an email. I can maybe tell you how to fix it, or I can fix it or at least do something with the parts to save others..
Now that I know my way around in them, they aren't so bad at all, it's just they are different from what the normal camera tech is used to I guess.
Problems I've seen so far:
Meter! The wires can be corroded from dead battery left in too long, the corrosion goes all the way from the battery to the circuit board, so the wire(s) have to be replaced. Not too hard.
The meter movement itself tends to stick due to little pads on the ends of the needle's travel stops. Once that's gone, the meter often is healed.
Also the meter movement is sort of massive compared to the frail way it is mounted on pivots, the whole meter movement is rotated by pushrods by the shutter speed dial. A good drop can knock the meter out of it's pivots. Not too hard to put back.
The shutter can seem to fail if the meter cell arm gets out of whack.. there is a soft plate with not enough fastners in it for my tastes that holds the meter arm hinge pin.. So the arm can get un hinged- the shutter can't release unless the arm is working right.
There is only one right way to get all the gears back together in the advance/winding geartrain, but it's not too hard to deduce.
The circuit board is quite simple and tough, pure ceramic and gold, so not too hard to keep alive..
Remember, the R is sort of derived from the CL, especially the finder. The whacky mechanical meter jazz in the cl has been replaced by a sort of annoying led display, and the silk shutter by an off-the-shelf metal one. Both great cameras, comparing them is like comparing a 1971 car to a 1999 one..
