Bert – 
I appreciate the education on this topic.  I learned a lot and thanks for taking the time to compose it.  So… I’ve seen reference to a, “Low-Wall, Thick-Wall”.
Would this be the first variation of the Low Wall?
  

I do not believe that to be the case.  I suspect it was someone’s attempt to describe a 2nd variation low-wall receiver frame.
