Actually, Frerking has an address in Nebraska, as I recall, in some tiny little town. They are not incorporated with the state, but I found address listings for them outside of Joeken. I don't know how they 'hooked up', but I suspect its somebodies brother in law, or something.
Ewbank is the 'ken' part of 'joeken'. They made a company to turn tapco flats into guns. They are right behind Joeken in Winslow AZ.
