Just amazes me how equipment manufactured in those days was built to last, with some of it still in use today, and in as good a shape as it was installed. Yet, with equipment manufactured these days, you are lucky if you get a few years out of it before it wears out or burns up...
Remember that there was junk made back then. It's just that almost all of it has long since wore out or broke, and had been replaced. Thus you rarely see antique low quality equipment today.
