Revell’s 727-100 is an old vintage kit. Being the -100, this means it is the short-body 727 with the oval intake for the center engine. If you want the newer -200 (long fuselage, round center engine inlet), plan to get either the Airfix or Minicraft kits. Being an old Revell kit, it has lots of rivets and raised details that you might want to consider sanding off since filling and sanding the seams will remove some of the detail anyway. The windows are shallow depressions, so you may want to use some filler and get window decals. One can come up with a nice model with this kit, but it will take a little work.
