During the early part of WW-II, and again from 1948 until 1959, Sears sold these under the Sears Dunlap badge at first and later under the Craftsman "80" badge. They were made by a company also in Michigan named AA, sometimes spoken as "Double A". The company and the lathes have no connection to Atlas or Clausing, although I have heard it said that their Change Gears are interchangeable with those on the Atlas 6". It has been a while but several of them have shown up and been discussed here. And there are a few manuals and parts drawings in Downloads under the same folder/Category as the Atlas machines.
