      Not the exact specs but close enough for a pica pole measurement. I have
      wondered if they had made the oscillating ink drum out of heavier gauge pipe if
      the added weight would have solved the roller chatter problem. The SP series had
      a very simple inking system compared to the #4's etc that they replaced. But
      those were heavy duty inking setups, but also costly to make, hence the "Simple
      Precision" models, also maybe should have been CC for 'cheap competitive"
      presses--they were facing Challenge, Reprex, plus the imports at that time, so
      Vandercook had to make an inexpensive series of presses that also worked.

      smaller than the Universal I or the SP-20, which are much more stable. Like I
      said, gravity helps.

      more extra parts you'd have to buy (at Boeing prices) when they went bad.
