In 1934, Vibroplex began advertising the “Martin Junior,” which was an Original on a 3” base instead of the standard 3.5” base. Except for the base width, everything else was the same as on the Original. However, Vibroplex had apparently been making the same bug on special order since about 1920.    (http://www.la.ca.us/frandy/early.html)
