Mark of a dedicated work force, hired for ability and willingness to learn -then demonstrate it, when many of the 'engineers' had sufficient mechanical background - hands on, and planned obsolescence rated sinful. When you build for longevity, even the machine frame, aka 'skid' can be pointed to with pride.
