The link below is to a page a guy set up when he was researching Dualmatic twin lever hubs for his Jeep. Nonetheless, interesting information.
I have a set of the later Dualmatic hubs with the large external knob. These were purchased by the original owner in the 1960's from Wilensky Auto Parts. I later purchased an identical NOS set from Wilensky in 1980. It is my understanding that Dualmatic of Longmont Colorado was the originator of this design. They were eventually bought out by Selectro, and later the design was passed onto Milemarker. It appears that the old Dualmatic design has stayed pretty much the same throughout its entire lifespan. Not sure how the current quality compares to the 1960's version though.
I also have a set of these same hubs with Perfect Circle markings in place of the Dualmatic name. I have seen these same hubs with other markings as well: Sears, IH, 4 Wheel Drive, Power Train Products, and B&M. It appears Dualmatic made them for several companies to put their names on them.
