When did Herters fold?
Early '70s?
I believe Herters closed down due to the 1968 gun control act.
Before that, you could order guns on-line. I had ordered a 357 and one of my brothers ordered a 44 Mag from them. They were much like a Hawes single action revolvers, I think.
When Herters in Mitchell, SD was closing, my dad and a couple of my brothers went there and bought every Weaver scope they in stock. I think I was in Camp Pendleton guarding prisoners at the time so I missed it. (I was in USMC - not positive where I was though.)
