Pre-GCA '68, Herter's was huge in sporting goods. George Herter was extremely agressive in pricing and marketing. I don't think they made much, if anything, but they sure had a lot of stuff made under contract to their specs. A lot of their reloading gear is still in use. They were after the user market. I don't think any of their stuff was really top quality, but it was almost all good enough and a few bucks cheaper.
They got hurt bad by GCA '68 and never recovered although they hung on for another decade or so. Much of their business was firearms related, including some proprietory cartridges. When all that had to go through an FFL dealer, that market died.
