The Alden Jobber Press is nothing more than a newer Daughaday Press with a different flywheel.  Once the Daughaday Company was sold off the rights to the Model press line went to Alden, shortly after that to another company which only put "Model #3 Jobber Press" on the flywheel.  The Alden Co. was based out of Cincinnati, Ohio..but it's unsure where the casting for these presses were foundered.  It is a clone of a Daughaday Model #3 treadle expect for the flywheel.  Alden Press Co. was short lived so there isn't to many Alden Presses out there...most were Daughaday or just Model #3 Jobber Presses.
