Type ACL 7 Air Compressor Cylinder Head for Gardner Denver Quincy 13988

  For sale is a Air Compressor Cylinder Head for Quincy (and possibly
  other brand) Air Compressors.  Unit is labeled: ACL-7.  It is also
  tagged (by last owner) "For Quincy Air Compressor, Ready to Install."
  There is a group of New and Unused gaskets that will come with the
  compressor cylinder-head.  NOTE: I cannot test this item, but have
  found that the (2) round components visible from the bottom of the
  head can be turned by hand.
