The Canon F-1 and FT/FTb/TX use no such resistors. There isn't anything to wear down on the metering circuit, save for the CdS cells itself. But i've yet to find one of those cameras with a aged (worn down, faulty) CdS cell or cells.
Technically the shutter speed and ISO part of the equation is factored in using a similar resistor, but I've never heard of it having any issues.
