Where in the world do you guys get Sterling in this ? Sterling is owned by Daimler Benz. Sterling never had anything to do with International.
Navistar is the same company as International Harvester. They renamed the company after the sale of the ag division. If you bought shares in IH before the sale of AG division you still had shares after the merger and to this day. Just the name of the company changed. Recently (fall of 2020) Traton, which is owned by Volkswagen is buying Navistar International. So The company that was formed in 1902 will be done soon.
