Sometimes things just keep working (Score 1)

I have a Western Electric Model 500 telephone, manufactured per the bottom plate May of 1963, but including older parts such as the black metal fingerwheel. I think the ringer needs to be adjusted for the voltage on my line, but its line cord has already been replaced with a modular one and it works great -- on cable company phone service no less. So it's working at upwards of 45 years, combination in-service and a few years in the attic. Obviously this is a simpler device than a computer, but electronics can hold up if they are built right.
