Thanks for the replies, This came from a factory I worked at. They buy (overpay) almost everything from Grainger. If the value of it is only 1 or 2 dollars I will just toss it in the scrap pile. I sure will not ever use it. Thanks again.
It might have been a generic tool made for the Grainger Westward brand. This doesn't mean it's ****, it might have been made by a toolmaker who mostly makes private label tools for other manufacturers or brands.
Stamping a brand mark would only cause problems or confusion for one of the brands if they wanted to mark it themselves.
If it is 25 years old it might have been made in the USA, Germany, Japan, Eastern Europe, Russia, or who knows were. There are manufacturers in all of these who would likely still make unbranded merchandise if someone orders a large enough quantity, or if business is slow and they don't want to risk damaging the value of their brand by selling an item at a lower cost.
I found this website listing a generic 3" OD Die holder priced at $96.99. I presume if someone needs a die holder this size you might be able to get $20 for it. I wouldn't scrap it.
