I Think you have what is known as a hardware store gun. At one time, companies would order guns from makers like Stevens, Mossberg, Marlin and Winchester, to be marked with their private label (Sears was best known for this with JC Higgins)
Val-Test was formed in 1962, in Chicago, and is still around- distributor of hardware, tools, etc. Now in Schaumburg IL.
What we have here is... failure- to communicate.
