For your consideration, here is the Seahawk and Boxer Add-On CD-ROM for Microsoft Flight Simulator 2004, from Aerosoft, 2005, with 67 page instruction manual.  The disc is in nice shape.  The manual is dented a little on the edge.  The case has some wear on it.  It will be mailed in a box for protection.  Item pictured is the actual item up for sale and comes from a non-smoking household.  (375.246j-.10dx4)
