I have a bunch of Herter's stuff and consider myself a casual collector, but I am not an expert and since I am too young to have lived (as an adult) during Herter's time, I have no residual memories. Ole' George contracted with many different people/companies and wasn't known to treat his vendors well. A couple other die and tool makers that came and went, as a vendor for Ole' George, was HF Wells and Bystrom (Minnesota Shooters Supply).
