With this slideshow, IndustryWeek continues its salute to US manufacturing's long and rich history.
This gallery represents an update to our ongoing salute to manufacturing longevity. The manufacturing firms identified in this gallery have been in business for at least 100 years, and for many of them, it's been far longer than that.
Thank you to the IW community. You continue to bring our attention to manufacturing companies that should be added to our salute, and we appreciate the notifications. The companies in this update are listed in alphabetical order. Enjoy. We plan to keep adding to these collections.
